95 mOhm Rds(on) and 45 nC gate charge — what they mean for the switching loop
The 95 mOhm on-resistance at 10 V Vgs and 11.8 A is the conduction loss anchor. The 45 nC total gate charge at 10 V tells you how much energy the driver must deliver per switching cycle.
Through-hole TO-220-3 — mounting and thermal path
Housed in a standard TO-220-3 (PG-TO220-3) through-hole package, this part bolts to a heatsink via the metal tab, which is electrically common with the drain. The 128 W maximum power dissipation at case temperature assumes ideal thermal interface.
Lifecycle and sourcing posture
For BOM planning, this means no forced redesign cycle from obsolescence. If your line needs a known-good cross, the CoolMOS C7 family includes several 650 V TO-220 devices with similar Rds(on) and gate charge profiles — confirm pin compatibility and thermal specs against your operating point before substituting.
