Forward voltage is 1.1 V typical at 22.5 A — half the rated current — which gives a conduction loss of roughly 25 W per diode pair at that operating point; the 4-SIP PB package's thermal impedance to the PCB copper must be sized to keep the junction below 150°C. Through-hole mounting in a 4-SIP PB (isoCINK+™ PB) package — the four pins route the AC inputs and DC output in a single in-line row, which simplifies the PCB trace layout for the high-current loops. Supplied in tube packaging; the isoCINK+™ PB package provides creepage and clearance distances for the 800 V peak rating without requiring a separate heatsink insulator in many designs. ## Lifecycle and compliance ROHS3 compliant, so no exemption expiry risk for EU-market BOMs. Reverse leakage is specified at 10 µA at the full 800 V blocking voltage — a clean blocking characteristic that avoids thermal runaway in high-line applications where leakage doubles with temperature.","metaTitle":"Vishay PB5008-E3/45 Bridge Rectifier, 800V 45A, 4-SIP PB","metaDescription":"Vishay PB5008-E3/45 single-phase bridge rectifier, 800 V peak reverse, 45 A average, ROHS3 compliant, active production.
