That 600 V rating gives you headroom on a 240 VAC mains line — the peak of a 240 V sine wave is about 340 V, so the 600 V PIV leaves margin for transients and line surges without avalanche stress. The forward voltage is specified at 1 V maximum when conducting 4 A — that is the conduction loss per diode pair. At 3 A average output, expect roughly 3 W of dissipation across the bridge, which the GBU package's copper leadframe can sink into the PCB or a small clip-on heatsink. Reverse leakage is just 5 µA at the full 600 V blocking voltage and 25 °C junction — low enough that it won't affect efficiency in a continuously running supply, but note that leakage doubles roughly every 10 °C rise, so at 125 °C junction it will be higher. ## Temperature range and deployment context A bridge rectifier in an outdoor telecom rectifier or an industrial power supply that sees 85°C ambient still has 65°C of margin before hitting the absolute maximum junction limit. The GBU package is a 4-pin single-in-line through-hole format with a standard 5.08 mm pitch. The copper tab on the package body is electrically live at the DC output potential — keep that in mind during layout if you plan to bolt a heatsink to it. ## Lifecycle and compliance posture Vishay lists the GBU4J-/45 as Active in production — no end-of-life notice, no last-time-buy window.","metaTitle":"Vishay GBU4J-E3/45 Bridge Rectifier, 600V 3A, GBU","metaDescription":"Vishay GBU4J-E3/45 single-phase bridge rectifier, 600V peak reverse, 3A average, GBU through-hole package.
