On-resistance and gate charge — the switching-loss trade-off
The STF7NM60N: The 900 mOhm Rds(on) at 2.5 A, 10 V is the on-resistance for this 600 V device. The 14 nC total gate charge at 10 V allows switching with a standard gate driver.
TO-220FP isolated package — no insulating pad needed
The TO-220-5 Full Pack (TO-220FP) is a fully moulded, isolated package — the back tab is electrically isolated from the die, so you can bolt it directly to a grounded heatsink without a silicone pad or mica washer. The through-hole mounting suits single-sided boards and manual assembly; the 20 W power dissipation at case temperature is the thermal budget to work with, and the 150°C maximum junction temperature allows a reasonable derating margin.
ROHS3 compliance covers the current regulatory requirements for lead-free assembly.
