The maximum gate threshold voltage is 2.35 V at 25 µA drain current, and the drive voltage range for rated Rds(on) is 4.5 V to 10 V. ## 175°C junction rating — thermal headroom for tight enclosures Power dissipation is rated at 65 W at case temperature. ## TO-220AB through-hole — mounting and thermal interface The IRLB8721PBF comes in a TO-220AB through-hole package. The through-hole format allows hand-rework and is preferred in point-of-load regulators where the PCB is single-sided or the assembly line does not run reflow.","metaTitle":"IRLB8721PBF HEXFET N-Channel MOSFET, 30V 62A TO-220AB","metaDescription":"IRLB8721PBF N-channel HEXFET MOSFET, 30V drain, 62A continuous, 8.7mOhm Rds(on) at 10V.
