KBU8B-E4/51 Description

Short technical summary and product information.

This Vishay Dale KBU8B-E4/51 is a single-phase bridge rectifier designed for general-purpose AC to DC full-wave rectification. It features a maximum repetitive peak reverse voltage (Vrrm) of 100V and an average forward rectified output current (If(AV)) of 8A at 100°C case temperature.

 

The rectifier has a high surge current capability of 300A (IFSM) and a low maximum instantaneous forward drop of 1.0V at 8A. The operating temperature range is from -50°C to 150°C (TJ).

 

Packaged in a KBU case, this component is suitable for printed circuit board (PCB) applications and utilizes through-hole mounting. It offers a high case dielectric strength of 1500 V RMS.

 

Typical applications include use in monitor, TV, printer, SMPS, adapter, audio equipment, and home appliances.
