Product details

The STWA45N65M5: Total gate charge is 82 nC at 10 V. Input capacitance is 3470 pF at 100 V drain-source.

Package and thermal budget

Housed in a TO-247 through-hole package, the part dissipates up to 210 W at the case. The junction temperature ceiling is 150°C. The TO-247's large tab area allows direct heatsink mounting with a thermal pad or grease — the thermal resistance from junction to case is the limiting factor in continuous power designs.

It is ROHS3 compliant.
