For a 240 VAC mains input, the peak voltage is 339 V, so the 400 V rating provides 61 V of headroom for line transients and surge events. Forward voltage is 1.25 V typical at 400 mA forward current. Two diodes conduct in series per half-cycle, so the total conduction drop is approximately 2.5 V at that current level. Reverse leakage is 5 µA at the full 400 V blocking voltage — low enough for always-on circuits where standby power matters. ## TO-269AA surface-mount footprint Packaged in the TO-269AA (MBS) 4-pin surface-mount package, the RMB4S-/45 occupies a compact footprint roughly 8.5 mm × 6.5 mm. The MBS outline is a standard for low-current bridge rectifiers and mates with conventional SMD solder pads. The device ships in tube packaging, not tape-and-reel — factor this into pick-and-place setup if the line expects reel-fed parts. The wide temperature range suits applications from outdoor telecom rectifiers to high-ambient power supplies.","metaTitle":"Vishay RMB4S-E3/45 Bridge Rectifier, 500 mA, 400 V, TO-269AA","metaDescription":"Vishay RMB4S-E3/45 single-phase bridge rectifier, 500 mA average rectified current, 400 V peak reverse voltage, TO-269AA surface-mount package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Diode Type":"Single Phase","Technology":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-269AA, 4-BESOP","lifecycle_stage":"eol_hot","Operating Temperature":"-55°C ~ 150°C (TJ)","Supplier Device Package":"TO-269AA (MBS)","Voltage - Peak Reverse (Max)":"400 V","Current - Reverse Leakage @ Vr":"5 µA @ 400 V","Current - Average Rectified (Io)":"500 mA","Voltage - Forward (Vf) (Max) @ If":"1.25 V @ 400 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9","priceTiers":[{"qty":1,"price":"$0.90000","currency":"USD"},{"qty":10,"price":"$0.80600","currency":"USD"},{"qty":100,"price":"$0.62850","currency":"USD"},{"qty":500,"price":"$0.51920","currency":"USD"},{"qty":1000,"price":"$0.42537","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/96137406bae2717bd1b2c0f77165e887.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/RMB4S-E3%2F45/alternatives.json"},"ai":{"faq":[{"question":"What is the diode type and technology of the RMB4S-/45?","answer":"It is a single-phase bridge rectifier using standard recovery silicon technology.
