4N80L MOSFET TO220F1 UTC 4A 800V UTC 4N80L

Product Overview:

The 4N80L is a high-voltage, through-hole N-Channel Power MOSFET manufactured by Unisonic Technologies (UTC). Engineered with advanced planar stripe and DMOS technology, this component minimizes on-state resistance while delivering superior, high-speed switching capabilities. The TO-220F1 package option features a fully over-molded plastic insulation, making it ideal for compact layouts where electrical isolation from the heatsink is required without separate hardware. It is extensively applied in high-efficiency switch-mode power supplies (SMPS), PWM controllers, motor drivers, and DC-DC converters.
