As PCIM Europe 2026 comes to an end, one thing stands out: innovation in power electronics continues to accelerate, driven by the engineers, designers, and developers turning complex challenges into practical solutions.

From discussions on AI server power supplies and energy efficiency to reliability, thermal management, and next-generation semiconductor technologies, we've enjoyed every opportunity to exchange ideas with the PCIM community.

If you're still at the exhibition, today is your last chance to visit us in Hall 9, Booth 434. Stop by to explore our demo boards, meet our team, and say hello to our newest team member — the Diotec fox mascot.

Two years after the drop-in passed parametric qualification, the field returns started.

The qualification missed what cycling would have caught.

Two parts with the same V_R, I_F, and package can differ in switching speed.

In reverse recovery.

In leakage at temperature extremes.

The harder gap is mechanical.
Lead frame construction.
Die attach material.

Mould compound.

None of it shows up in the parametric table.

It shows up in cycling.

In a non-safety-critical design, you absorb the gap and revisit if something fails in service.

In an automotive design, the gap is the qualification work.

AEC-Q101 requalification is not a paperwork exercise.

Same parametric verification, same stress testing, same process control review the original went through.

Including the cycling that catches what the parametrics miss.

The PCN lands.
The engineering team has months ahead.
The program is asking when the part will be back in production.

Second-source qualification has to happen before the substitute is needed.

Drop-in is a sourcing label.

Qualification is an engineering one.

PCIM Europe 2026 is officially underway!

If you're visiting the exhibition, we would be delighted to welcome you at the Diotec Semiconductor AG booth in Hall 9, Booth 434.

Our team is available throughout the event to discuss your applications, answer technical questions, and explore how our semiconductor solutions can support your next design. We are also showcasing a selection of demo boards, giving visitors the opportunity to take a closer look at our technologies and their real-world applications.

🦊 There is another new face at our booth this year: our brand-new Diotec fox mascot!

To celebrate its debut, we are running a prize competition throughout the exhibition. Visit our booth, suggest a name for our mascot, and enter for a chance to win the grand prize. We are looking forward to seeing your creativity!

Additionally, don't miss our Exhibitor Stage presentation by our Senior Product Manager Udo Steinebrunner:
AI and the Need for Super Efficient Data Server Power Supplies
📅 10 June 2026
⏰ 12:30–12:50
📍 Hall 4A, Stage 320

Join us for insights into the growing power-efficiency demands of AI-driven data infrastructure and the semiconductor technologies helping to address them.

We look forward to meeting you in Nuremberg and having some inspiring technical discussions over the next few days.

Nobody unplugs a battery on purpose.

But it happens.

A loose terminal.
A technician working under the hood with the engine running.
A vibration that finally wins.

The moment that connection breaks, the alternator, still spinning, still generating, has nowhere to send its current.

So it sends it everywhere.

The voltage on that 12V rail surges.
Unclamped, it can peak above 120V.
And it doesn’t disappear instantly.

It can take up to 400 milliseconds to decay.
Every control unit on that line sees it.

The ECU. The BMS.
The actuator drivers.

Circuits designed for 12V, suddenly buried under a spike they were never rated for.

This is 𝗹𝗼𝗮𝗱 𝗱𝘂𝗺𝗽.
It’s a defined test condition in 𝗜𝗦𝗢 16750-2 because it happens in the real world, and it destroys real hardware.

5.0𝗦𝗠𝗖𝗝28𝗔-𝗔𝗤 clamps it.

In 𝗗𝗢-214𝗔𝗕.
Before the spike reaches what’s behind it.
TVS technology responds in picoseconds.

This component absorbs 5000𝗪 of peak pulse power, holds the voltage below 45.4𝗩, and keeps doing it reliably enough to carry 𝗔𝗘𝗖-𝗤101 qualification and 𝗣𝗣𝗔𝗣 capability.

ICE, HEV, BEV.
They all still run a 12V system.

The risk doesn’t disappear because the powertrain changed.

The protection has to be there before the field finds it for you.

The booth is ready, the team is excited, and we're all set for PCIM 2026! 🚀

After a busy setup day with my great colleagues, we're looking forward to welcoming visitors starting tomorrow.

If you're attending PCIM, make sure to stop by our booth # 9-434. We have plenty of great giveaways waiting for you, and every visitor will have the chance to win a special prize by helping us name our brand-new mascot. 🎁

Come say hello, meet the team, discover our latest solutions, and join the mascot naming challenge.

See you at PCIM!

Success in sport is not only measured by results, but also by the ability to learn, adapt, and come back stronger.

At the Formula Kite World Championship in Portugal, Jan Matthis Vöster faced a challenging week that did not unfold as planned. Yet his reflections demonstrate the mindset that drives long-term success: taking responsibility, learning from setbacks, and staying focused on the next opportunity.

We are proud to support athletes who embody resilience, determination, and continuous improvement — values that resonate strongly with us at Diotec.

Thank you, Jan, for sharing your honest insights. We look forward to following your journey and cheering you on at the next race.

Most PCB failures aren't caused by the big components.

The discretes. The passives.
The "we'll sort that in layout" components.

A missing pull-down resistor.
A base current that wasn't properly limited.
A transistor that stays partially on when it should be off and takes a relay with it.

The MMDTC143HP eliminates that risk before layout even starts.

Both bias resistors integrated - 4.7 kΩ input, 47 kΩ base-emitter - one package. 1.0 × 0.6 mm.

The circuit is stable by design, not by hope.

50 V. 100 mA. 0.38 mm tall.

One component replaces three.
Your first-time-right ratio just got a defensible argument.

At Diotec Semiconductor AG, we believe innovation thrives where passion meets hands-on engineering.

That’s why we’re proud to support the dedicated students of Racetech Racing Team TU Bergakademie Freiberg e.V. at Technische Universität Bergakademie Freiberg. We contribute selected semiconductor components to help powering their Formula Student race cars.

It’s always inspiring to see what talented young engineers can achieve with the right tools — and a lot of determination. The Racetech team continues to impress us with their technical excellence, creativity, and team spirit.

We’re glad to play a small part in their journey and look forward to seeing them on the track. 🏎️

The thermal resistance in the datasheet is a measurement, not a property.

RthJA tells you what junction temperature you'd see if your PCB matched the JEDEC reference board. It usually doesn't.

JEDEC test boards have specified copper area, specified thickness, specified airflow, specified ambient. Your design has different copper area, different thermal vias, different adjacent components, different airflow, different ambient.

The RthJA on the datasheet isn't wrong. It just isn't yours.

This is why two engineers calculating the same junction temperature with the same part can get the same number and see different results in service.

The calculation says 95°C. The bench says 110°C.

Most of the gap is the PCB.

A part's RthJC is closer to a property of the package. It still depends on how it's measured, but it's less hostage to what's outside the part than RthJA. If you can measure case temperature in your actual design, you can work backward to a junction temperature grounded in your reality, not in JEDEC's.

This matters more in sealed enclosures, more in densely populated boards, more at higher ambient. It matters most where modern designs are heading.

The datasheet gives you a reference number. Your design gives you the answer.
