Product details

Rds(on) and gate drive — what 78 mOhm at 10 V means

The STB45N65M5: The 91 nC total gate charge at 10 V and 3375 pF input capacitance at 100 V Vds define the switching energy per cycle.

D²PAK footprint and thermal path

The STB45N65M5 comes in a D²PAK (TO-263) surface-mount package with the tab as the drain terminal.

ROHS3 compliant. No official second-source or successor cross-reference is listed, so the BOM line is single-sourced to ST.
