KBP04M-E4/51

Overview

The KBP04M-E4/51 is a single-phase standard bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage of 400 V and an average forward rectified current of 1.5 A. The device exhibits a maximum forward voltage drop of 1.1 V at 3.14 A and a leakage current of 5 µA at 1000 V. Designed for through-hole mounting in the 4-SIP, KBPM package, it operates within a junction temperature range of -55°C to 150°C. The component complies with RoHS3 standards and carries an MSL rating of 1.

Feature Summary

• Single-phase bridge rectification architecture
• Through-hole installation via KBPM package
• High-temperature operation capability up to 150°C

Applications

• General-purpose AC to DC conversion circuits
• Power supply input stages
• Bridge rectifier applications requiring 400V isolation

Procurement Notes

Verify component authenticity upon receipt as the part number may be obsolete or discontinued. Confirm that the received units match the specified 4-SIP, KBPM package and electrical ratings. Check for manufacturing date codes and compliance markings such as RoHS3 status. Ensure storage conditions maintain moisture sensitivity level 1 integrity before soldering.

Selection Notes

Select this component when a 1.5 A current rating and 400 V reverse voltage are required for single-phase rectification. The KBPM through-hole package suits designs needing robust mechanical mounting. Verify thermal management requirements given the 150°C junction limit. Compare against similar Vishay KBP series variants if specific suffixes affect pinout or packaging.

Part Context

This component belongs to the KBP series of bridge rectifiers from Vishay. The KBP series typically offers various voltage ratings including 400V, 600V, 800V, and 1000V options. The 'E4' suffix indicates lead-free composition compliant with EU directives. The '/51' suffix often denotes specific tape-and-reel or bulk packaging configurations depending on distributor data.
