250 V, 8 A N-channel in DPAK — switching converter workhorse
It targets offline flyback converters, auxiliary power supplies, and 48–72 V telecom DC-DC stages where the 250 V drain-source rating provides margin for reflected-voltage spikes and line transients.
420 mOhm on-resistance — conduction loss at 8 A
The 16 nC typical gate charge at 10 V keeps the gate-drive current modest for a 250 V part; a 100 kHz hard-switched converter draws about 1.6 mA from the driver, well within a standard gate-drive IC's output.
At the high end, the 420 mOhm Rds(on) doubles per the normalised curve — the designer must derate the continuous drain current from 8 A at 25°C case to roughly 4 A at 150°C junction to stay inside the SOA.
