Housed in the KBL 4-SIP through-hole package (supplier device package KBL), it is suited for board-level power conversion where a compact, single-inline footprint is needed. ## Forward drop and leakage — the thermal budget drivers Reverse leakage is specified at 5 µA at the 400 V peak reverse voltage — low enough that self-heating from leakage is negligible across the operating temperature range.","metaTitle":"Vishay KBL04-E4/51 Bridge Rectifier, 400 V, 4 A, KBL Package","metaDescription":"Vishay KBL04-E4/51 single-phase bridge rectifier, 400 V peak reverse, 4 A average output, KBL through-hole package, RoHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Diode Type":"Single Phase","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"4-SIP, KBL","lifecycle_stage":"eol_hot","Operating Temperature":"-50°C ~ 150°C (TJ)","Supplier Device Package":"KBL","Voltage - Peak Reverse (Max)":"400 V","Current - Reverse Leakage @ Vr":"5 µA @ 400 V","Current - Average Rectified (Io)":"4 A","Voltage - Forward (Vf) (Max) @ If":"1.1 V @ 4 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.58","priceTiers":[{"qty":1,"price":"$1.58000","currency":"USD"},{"qty":10,"price":"$1.41100","currency":"USD"},{"qty":100,"price":"$1.10000","currency":"USD"},{"qty":500,"price":"$0.90872","currency":"USD"},{"qty":1000,"price":"$0.74448","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/04e6d1e8054af0e7573510d6c848ee48.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/KBL04-E4%2F51/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/KBL04-E4-51","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/KBL04-E4-51 when reusing this data.
