600V/650V automotive-grade MDmesh™ DM9 super-junction power MOSFETs

More efficient with higher power density

A step forward in hard and soft switching and improved system ruggedness with fast intrinsic diode​

A step forward in hard and soft switching and improved system ruggedness with fast intrinsic diode​

Our 600V/650V automotive-grade MDmesh DM9 power MOSFETs offer outstanding RDS(on) and Qg with low recovery charge and time. With excellent static and dynamic performance, these devices reduce both turn-off and turn-on switching power losses, resulting in high-efficiency bridge topologies and ZVS phase-shift converters. The portfolio will soon include top-side cooling packages for space-saving, higher efficiency, and better thermal dissipation. 
The STH60N099DM9-2AG in a H2PAK-2L package is the first DM9AG device in production.
