In a 2 A offline flyback primary switch, that resistance contributes roughly 1.7 W of I²R loss at full load — within the 83.3 W package power dissipation ceiling, but the designer must account for the Rds(on) positive temperature coefficient when the junction climbs above 25°C.
Gate charge and switching loss budget
Total gate charge is 31.5 nC at 10 V, with an input capacitance of 870 pF measured at 100 V drain-source. For a hard-switched converter running at 100 kHz, the gate-driver current required to charge and discharge Qg in the dead time is about 3.15 mA average — well within the capability of a standard MOSFET driver IC. The low Qg relative to the 650 V class keeps crossover switching losses manageable, which matters for PFC stages and LLC converters where the MOSFET sees both hard turn-on and zero-voltage transitions.
Package and thermal interface
The part ships in a TO-263-3 (D²Pak) surface-mount package, supplier device code PG-TO263-3-2.
Lifecycle and compliance
It is ROHS3 compliant. No official second-source or pin-compatible alternate is listed in the manufacturer's cross-reference, so dual-sourcing would require qualification of a functionally equivalent CoolMOS or competitor device.
