500 V, 12 A CoolMOS N-channel — the conduction loss and switching drive picture
The Infineon IPA50R299CPXKSA1079 is a 500 V, 12 A N-channel CoolMOS MOSFET in a TO-220 Full Pack through-hole package.
Gate charge and input capacitance — what drives the switching speed
For a hard-switched converter running at 100 kHz, the average gate-drive current needed is roughly 3.1 mA — a standard 1 A gate driver handles the peak charge current without issue.
Full-pack isolation and temperature grade
The TO-220 Full Pack (PG-TO220-3-31) encapsulates the backside drain tab in moulding compound, providing galvanic isolation between the tab and the heatsink — no insulating pad or washer is needed, which simplifies assembly and reduces thermal resistance through the package back.
