Keeping EVs Cool Under Pressure – Powered by Diotec MOSFETs

Modern electric vehicles rely on high-performance coolant pumps to manage the heat generated by the battery and powertrain - especially during demanding fast charging cycles. In all-wheel drive EVs, these pumps often cool multiple electric motors simultaneously, requiring efficient, powerful, and reliable solutions. At the core of these 120 W to 300 W brushless DC pumps, operating on 12 V to 48 V systems, is a rugged and dependable power stage—driven by Power MOSFETs.

Introducing the DI065N08D1-AQ by Diotec Semiconductor:

A 65 A / 80 V Power MOSFET in a compact TO-252AA / D-PAK package, designed for demanding automotive BLDC motor control applications.

Key Specs:

  • RDS(on) < 7mΩ
  • Max junction temperature: 175°C
  • Logic-level gate drive
  • Low gate charge → ideal for fast switching
  • Built for long-lasting performance in harsh environments

This is the kind of robust solution that keeps EV coolant systems running efficiently for years.
