Description

Marked "GBJ15J" on the package, this is a GBJ15J (often produced by manufacturers like Diodes Incorporated / Diodes Inc.), a 600V, 15A single-phase glass passivated bridge rectifier. It is designed to convert alternating current (AC) into direct current (DC). Featuring high forward surge current capability, low reverse leakage, and high dielectric strength, it includes a mounting hole for easy heat-sink attachment in high-power conversion stages.
