Technical details

900 V N-channel — the high-voltage workhorse in a DPAK

6.5 Ohm Rds(on) — conduction loss budget

Maximum on-resistance is 6.5 Ohm at Vgs=10 V and Id=1.05 A.

Gate charge and input capacitance — driver sizing

These numbers are moderate for a 900 V device — a typical gate driver with 1 A peak output can switch this MOSFET in the tens of nanoseconds, keeping crossover losses manageable in a 100 kHz flyback or PFC stage.

Temperature range and thermal limits

The 150°C ceiling means the part can handle brief overloads, but continuous operation near the limit requires careful heatsinking.

It is RoHS3 compliant.
