KBU4G-M3/P

Overview

The KBU4G-M3/P is a single-phase standard bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 4 A. The device utilizes a through-hole KBU package, designed for robust mounting in power supply applications. Key electrical characteristics include a maximum forward voltage drop of 950 mV at 4 A and a non-repetitive peak surge current capability of 100 A. The component operates within a junction temperature range of -50°C to 150°C.

Feature Summary

• Single-phase bridge rectifier configuration for AC-to-DC conversion
• Standard recovery technology optimized for general-purpose power applications
• Through-hole KBU package design for secure mechanical mounting

Applications

• General purpose power supplies
• Battery chargers
• Adapters and converters

Procurement Notes

Verify the specific suffix '/P' against official Vishay documentation to confirm packaging details, as suffixes can indicate variations in tape-and-reel specifications or marking codes. Ensure the procurement channel provides traceable source data matching the manufacturer's part identification. Cross-reference the datasheet revision date to confirm the validity of the 400 V and 4 A ratings prior to finalizing purchase orders.

Selection Notes

Select this component when a 400 V reverse voltage rating and 4 A continuous current capacity are required for single-phase rectification. The KBU package offers a balance of thermal performance and board space efficiency for through-hole designs. Consider the 950 mV forward voltage drop for efficiency calculations in low-voltage output stages. Ensure the application environment stays within the specified -50°C to 150°C junction temperature range for reliable operation.

Part Context

This part belongs to Vishay's KBU series of bridge rectifiers, which are widely used in industrial and consumer electronics. The 'M3' designation typically indicates lead-free composition compliant with EU directives, while '/P' denotes the specific packaging format. This series is distinct from Vishay's fast recovery or Schottky bridge offerings, focusing on standard recovery performance for cost-effective power solutions.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the KBU4D-M3/P, which shares the same manufacturer and package but differs in voltage rating. Verify that any replacement matches the 400 V requirement and 4 A current rating. Check pinout compatibility and thermal characteristics before substituting.
