Gate charge and switching-loss budget
The IPA65R190C7: The threshold voltage (Vgs(th)) max is 4 V at 290 µA drain current — this is the turn-on edge; a gate drive that pulls below 4 V risks the MOSFET operating in the linear region during switching, increasing dissipation.
TO-220 Full Pack mounting and thermal budget
Housed in a PG-TO220 Full Pack (TO-220-3) with through-hole mounting — the full-pack variant has a fully insulated backside, so no thermal pad or insulating washer is needed against the heatsink; the tab is electrically isolated, simplifying heatsink attachment and reducing system assembly cost. Maximum power dissipation is 30 W at case temperature (Tc), and the operating junction temperature range spans -55°C to 150°C — the 30 W ceiling assumes an ideal heatsink; real-world dissipation is derated by the thermal resistance of the interface and the ambient conditions.
