PB5008-E3/45 Description

Short technical summary and product information.

The PB5008-E3/45 is a single-phase bridge rectifier from Vishay General Semiconductor, designed for general purpose AC/DC full wave rectification. It features a repetitive peak reverse voltage of 800V and an average rectified forward current of 45A when mounted with a heatsink (4.5A without heatsink). The typical forward voltage is 0.90V at 22.5A, and it can handle non-repetitive surge currents up to 450A. The I²t rating is 840 A²s, making it suitable for applications with high inrush currents.

The device is packaged in a through-hole 4-SIP PB (isoCINK+™ PB) case, which offers enhanced thermal conductivity. It is UL 1557 recognized (file E312394) with dielectric testing to 1500V and meets UL 94 V-0 flammability rating. The operating junction temperature range is -55°C to 150°C. Typical applications include switching power supply input rectification, home appliances, and white goods.

Mounting torque should not exceed 10 cm-kg, with a recommended torque of 5.7 cm-kg. The component is RoHS-compliant (industrial grade, suffix E3) and has matte tin plated leads solderable per J-STD-002.
