The 1.05 V forward drop at 12.5 A pulsed current means conduction loss in the bridge is manageable for a 3.5 A continuous load, but the peak surge rating is what handles the inrush into a discharged capacitor bank at power-on. Reverse leakage is 5 µA at 600 V — low enough that the bridge does not contribute significant standby power in a lightly loaded offline supply. ## Temperature grade and environment The through-hole 4-SIP BU package (isoCINK+™ BU) is a standard SIP footprint — it sits upright on the PCB with the tab for heatsink attachment, which is the expected mounting for a bridge in a convection-cooled supply.","metaTitle":"Vishay BU2508-E3/45 Bridge Rectifier, 800V, 3.5A","metaDescription":"Vishay BU2508-E3/45 single-phase bridge rectifier, 800V peak reverse, 3.5A average rectified current, through-hole 4-SIP BU package, ROHS3 compliant, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tray","Diode Type":"Single Phase","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"4-SIP, BU","lifecycle_stage":"eol_hot","Operating Temperature":"-55°C ~ 150°C (TJ)","Supplier Device Package":"isoCINK+™ BU","Voltage - Peak Reverse (Max)":"800 V","Current - Reverse Leakage @ Vr":"5 µA @ 600 V","Current - Average Rectified (Io)":"3.5 A","Voltage - Forward (Vf) (Max) @ If":"1.05 V @ 12.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.99","priceTiers":[{"qty":1,"price":"$2.99000","currency":"USD"},{"qty":10,"price":"$2.68200","currency":"USD"},{"qty":25,"price":"$2.53520","currency":"USD"},{"qty":80,"price":"$2.19725","currency":"USD"},{"qty":230,"price":"$2.08452","currency":"USD"},{"qty":800,"price":"$1.87045","currency":"USD"},{"qty":1600,"price":"$1.75395","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a3235e55ab6dbca851b17a401e1a3d83.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BU2508-E3%2F45/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/BU2508-E3-45","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/BU2508-E3-45 when reusing this data.
