KBL04/1

Overview

The KBL04/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak reverse voltage of 400 V and an average forward current rating of 4 A. The device utilizes standard technology and is housed in the KBL package, which supports through-hole mounting. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at 4 A and a maximum reverse leakage current of 5 µA at 400 V. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Single-phase AC-to-DC conversion capability
• Through-hole mountable KBL package design
• Standard rectifier technology for general applications

Applications

• AC-to-DC power supply circuits
• General purpose rectification in electronic equipment
• Battery charging systems

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to ensure correct pinout and electrical ratings. Confirm RoHS compliance status and packaging type requirements prior to ordering. Cross-reference the manufacturer part number with authorized distributor catalogs to validate availability and authenticity. Ensure application voltage and current limits remain within the specified 400 V and 4 A parameters.

Selection Notes

Select this component for applications requiring moderate current handling and standard reverse voltage blocking. The 4 A average forward current and 400 V peak reverse voltage define the operational boundaries. Consider the thermal management requirements associated with the 1.1 V forward voltage drop at full load. The through-hole KBL package facilitates easy integration into conventional PCB layouts.

Part Context

The KBL04/1 belongs to the KBL series of single-phase bridge rectifiers from Vishay. This series is designed for general-purpose rectification tasks. The device represents a standard solution for converting alternating current to direct current in various electronic assemblies. It complements other Vishay diode products offering similar or higher performance specifications.

Replacement Considerations

Compatible substitutes include the KBL04 and KBL04-M3/P. Verify that alternative components match the 400 V reverse voltage and 4 A forward current ratings. Ensure the replacement maintains the same KBL package footprint and pin configuration for direct board compatibility.
