KBU8M-E4/51 Description

Short technical summary and product information.

The Vishay Dale KBU8M-E4/51 is a single-phase bridge rectifier suitable for general-purpose AC/DC full-wave rectification applications. It is designed for use in devices such as monitors, TVs, printers, SMPS, adapters, audio equipment, and home appliances.

 

This bridge rectifier features a maximum average forward current of 8.0 A at 100°C case temperature and 6.0 A at 40°C ambient temperature. It has a high surge current capability of 300 A and a maximum forward voltage drop of 1.0 V at 8.0 A. The maximum repetitive peak reverse voltage is 1000 V, with a maximum DC blocking voltage of 1000 V and a maximum RMS voltage of 700 V.

 

Operating within a temperature range of -50°C to 150°C (TJ), the KBU8M-E4/51 has a maximum junction temperature of 150°C. It is housed in a KBU package with a Through Hole mounting type. The molding compound meets UL 94 V-0 flammability rating, and the terminals are silver-plated for solderability.

 

Key electrical characteristics include a maximum DC reverse current of 10 μA at 25°C and 1.0 mA at 125°C. The device is RoHS3 compliant and has an MSL rating of 1.
