Vishay Bridge Rectifier 800 V 150 A 4-Pin Single Through Hole BU12 Package BU1208-E3/45

Vishay BU1208-E3/45 Bridge Rectifier is a high-current density, single in-line package (SIL) designed to convert alternating current (AC) input into direct current (DC) output via full-wave rectification. Featuring a peak reverse repetitive voltage (VRRM) of 800 V and a forward current rating of 12 A, it is engineered for applications requiring robust and efficient power conversion.

The rectifier package uses Vishay's enhanced isoCink+ technology, providing superior thermal conductivity and improved reliability in a compact through-hole mounting format. With a peak forward surge current (IFSM) of 150 A, it supports transient current surges common in switching power supply and home appliance environments.

Operating safely within a temperature range from -55°C to 150°C, this bridge rectifier allows usage in demanding industrial, manufacturing, and electrical equipment applications. Its four-pin, single-phase configuration ensures ease of PCB soldering and stable electrical connections.

The diode features a low peak forward voltage drop at 1.05 V and a low peak reverse current of 250 μA, contributing to energy efficiency and low heat generation during operation. The compact dimensions (length 22.3 mm, height 18.8 mm, and width 4.1 mm) make it suitable for space-constrained designs.

This Vishay bridge rectifier complies with UL 1557 for the safety of electrically isolated semiconductor devices but does not possess additional certifications or automotive ratings. It is mainly used in power supplies for home electrical appliances, white goods, and other industrial electronics requiring reliable AC/DC conversion.

Supports peak reverse repetitive voltage of 800 V for efficient voltage handling. Rated forward current of 12 A and peak surge forward current of 150 A ensures robust performance. Constructed with enhanced isoCink+ SIL package for superior thermal conductivity.

Four-pin through-hole mounting facilitates soldering on printed circuit boards. Operating temperature range from -55°C to 150°C for broad application resilience. Single-phase Bridge Rectifier configuration suitable for linear and switching power supplies.

Compact size with dimensions 22.3 mm length, 18.8 mm height, and 4.1 mm width. Peak forward voltage of 1.05 V and peak reverse current of 250 μA for efficient diode performance.
