The 29 nC total gate charge at 10 V means a simple gate-driver IC can switch it without a lot of drive current. ## Through-hole TO-220 — field-swappable, no hot air needed The TO-220AB through-hole package is a field-service favourite. You can swap it with a soldering iron and a desoldering pump — no hot-air station, no preheater. The tab is the drain, so orientation is obvious once the part is in your hand. ## Active lifecycle, ROHS3 — no obsolescence clock No last-time-buy notice, no end-of-life date on the horizon.","metaTitle":"IRFB4020PBF N-Channel MOSFET, 200V 18A TO-220AB","metaDescription":"IRFB4020PBF N-Channel MOSFET, 200V drain, 18A continuous, 100mOhm Rds(on) at 10V.
