600 V, 10 A N-channel in a TO-251 — right-sized for offline flyback and PFC
It comes in a through-hole TO-251 (IPAK) package with short leads, intended for high-voltage DC-DC converters, flyback supplies, and power-factor-correction stages where board space is tight but a through-hole anchor is preferred over a surface-mount DPAK.
The 540 pF input capacitance at 50 V drain bias confirms the gate charge figure: the driver sees a moderate capacitive load, so rise and fall times stay under control even with a 10-15 Ohm series gate resistor.
Thermal and mechanical — the TO-251 package reality
The TO-251 (IPAK) package dissipates up to 70 W at the case, but that assumes the tab is soldered to a copper island on the PCB or clamped to a heatsink. In a typical through-hole layout with no added heatsink, the effective power dissipation drops to roughly 2-3 W before the junction hits 150 °C.
