650 V CoolMOS C7 in a through-hole full-pack package
65 mOhm on-resistance and 64 nC gate charge — the switching-loss trade-off
Gate charge is 64 nC at 10 V. Input capacitance is 3020 pF at 400 V drain-source.
Full-pack isolation and the thermal budget
The TO-220 Full Pack (PG-TO220-FP) encapsulates the backside drain contact in epoxy, so the mounting tab is electrically isolated. This saves a sil-pad or mica washer in grounded-heatsink assemblies, but the thermal penalty is real: the package is rated for 34 W power dissipation at case temperature, compared to roughly 80–100 W for a standard TO-220 with the same die. Derating for ambient temperature is mandatory — at 85°C case the allowable dissipation drops to about 22 W.
The base product number IPA65R065 covers the die and package variant; the XKSA1 suffix specifies the TO-220 Full Pack with standard lead finish.
