The 400 V peak reverse rating covers 120 VAC and 240 VAC mains with margin — after derating for line transients, the 400 V PIV keeps the junction safe. Reverse leakage is 5 µA at 400 V and 25°C — negligible for a standby supply, but leakage doubles roughly every 10°C junction rise, so at 125°C it approaches 320 µA. That matters for a bias supply that idles at high ambient; the leakage current adds to the output ripple and raises the no-load dissipation.","metaTitle":"Vishay B4S-E3/80 Bridge Rectifier, 400 V, 500 mA, TO-269AA","metaDescription":"Vishay B4S-E3/80 single-phase bridge rectifier, 400 V peak reverse, 500 mA average, 1 V forward drop.
