Product details

650 V CoolMOS for hard-switching power stages

The device is housed in a TO-262-3 (I²Pak) through-hole package (PG-TO262-3-1), which supports the 156 W power dissipation rating when mounted to an adequate heatsink.

Conduction and switching losses at the BOM level

The 280 mOhm Rds(on) at 10 V gate drive sets the conduction loss floor: at 9.4 A drain current the voltage drop is about 2.6 V, and the I²R loss reaches roughly 25 W — well within the 156 W dissipation limit when the case is held at 25°C.

Temperature range and mounting constraints

The PG-TO262-3-1 supplier package code matches the standard I²Pak footprint.

It is ROHS3 compliant, which simplifies compliance for EU and global markets.
