PB4008-E3/45 Description

Short technical summary and product information.

The PB4008-E3/45 is a single-phase bridge rectifier from Vishay General Semiconductor. It features a repetitive peak reverse voltage (VRRM) of 800V and an average rectified forward current (IF(AV)) of 40A when mounted on a heatsink (TC=87°C) or 4.4A in free air at 25°C. The forward voltage drop is typically 0.94V at 20A forward current, contributing to efficient operation. Reverse leakage current is limited to 10 µA maximum. The device can handle a non-repetitive peak surge current of 400A and has an I²t rating of 664 A²s for fuse coordination.

The rectifier uses standard silicon technology with glass passivated chip junctions and is housed in a compact 4-SIP PB through-hole package (isoCINK+™ PB). It features matte tin plated leads and supports a maximum mounting torque of 10 cm·kg (8.8 in·lbs) with a recommended torque of 5.7 cm·kg (5 in·lbs). The junction and storage temperature range is -55°C to 150°C.

Typical applications include AC/DC full wave bridge rectification in switching power supplies, home appliances, and white goods. The part is RoHS3 compliant as indicated by the E3 suffix and is recognized under UL 1557 (file E312394).
