That Qg number tells the gate-driver designer the energy per switching cycle — at 20 kHz switching, the average gate current is 4.4 mA, easily handled by a standard driver, but the peak current during the Miller plateau determines the rise time and the cross-conduction window. ## Through-hole TO-220AB — thermal and mechanical fit The TO-220AB package with through-hole mounting suits designs where the PCB is the primary heatsink or where a clip-on heatsink is acceptable.","metaTitle":"IRFB3077PBF HEXFET N-Ch MOSFET, 75V 120A TO-220AB","metaDescription":"IRFB3077PBF N-channel HEXFET MOSFET: 75V Vdss, 120A Id, 3.3mOhm Rds(on) max at 75A/10V.
