The Part That Cools Your EV Has to Survive Its Own Heat First

Modern electric vehicles rely on brushless DC coolant pumps to move heat away from batteries and inverters and drive units. They run continuously under vibration and voltage ripple and high ambient temperatures, exactly where silicon stress adds up fastest.

Hence - our engineers designed the DI100N10PQ-AQ:

→ A 100 A / 100 V Power MOSFET in a state-of-the-art QFN 5 × 6 mm package.

Built for harsh automotive environments:

→ RDS(on) < 5 mΩ

→ Logic-level gate drive

→ 175 °C max junction temperature

→ AEC-Q101 qualified, PPAP capable

→ Low gate charge for efficient switching

Those numbers aren’t just nice for a data-sheet.

They’re what keep high-current automotive systems efficient - for years.

Because in an EV…

The part that keeps the motor cool shouldn’t be the one that overheats first.
