800 V N-channel in a TO-252 — the switching converter workhorse
Packaged in a TO-252-3 (DPak) surface-mount case, it targets high-voltage offline switch-mode power supplies, flyback converters, and PFC stages where the 800 V rating gives headroom for universal-input AC-DC designs.
On-resistance and gate charge — the efficiency trade-off
The 10 nC total gate charge at 10 V keeps driver losses low and enables switching frequencies above 100 kHz in resonant or quasi-resonant topologies. The 250 pF input capacitance at 500 V drain-source confirms the low-Qg profile; the driver sees a light capacitive load, which simplifies gate-drive transformer design in isolated converters.
Temperature range and thermal budget
The 32 W maximum power dissipation at case temperature assumes a well-designed PCB copper area under the TO-252 tab — skimp on the pour and the thermal resistance climbs fast.
