KBL08-M3/P

Overview

The KBL08-M3/P is a single-phase standard bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V maximum repetitive peak reverse voltage and supports a continuous average forward rectified current of 4 A. The device utilizes the KBL through-hole package, designed for robust mounting in power supply applications. Key electrical characteristics include a maximum non-repetitive surge current rating of 150 A and a low forward voltage drop to minimize conduction losses. Operating temperatures range from -55°C to +150°C junction temperature, ensuring reliability under varying thermal conditions.

Feature Summary

• Single-phase bridge rectifier configuration for AC-to-DC conversion
• High surge current capability for transient protection
• Low forward voltage drop for improved efficiency
• Extended operating temperature range for harsh environments

Applications

• General purpose power supplies
• Battery chargers
• Inverter circuits

Procurement Notes

Verify the specific suffix /P indicates bulk packaging rather than tape-and-reel when reviewing distributor listings. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the exact KBL package dimensions required for your PCB footprint. Cross-reference the datasheet revision date to ensure all electrical parameters are current before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high reverse voltage blocking up to 800 V with moderate current handling at 4 A. The KBL package offers a cost-effective solution for through-hole assembly compared to surface-mount alternatives. Consider the thermal management requirements given the 150 A surge rating and junction temperature limits. Evaluate the forward voltage characteristics against system efficiency targets for optimal performance in standard rectification tasks.

Part Context

This component belongs to Vishay's KBL series of bridge rectifiers, widely used in industrial and consumer electronics. The KBL package provides a compact form factor suitable for various power density requirements. As a standard recovery device, it balances switching speed and cost for general-purpose applications. The product line is supported by extensive design-in resources and application notes from the manufacturer.

Replacement Considerations

GBL08-M3/51 is listed as a discontinued alternative by DigiKey, with GBL08E-E3/A available as a similar replacement. Verify pinout compatibility and package dimensions between KBL and GBL variants before substitution. Check if the alternative meets the same 800 V and 4 A specifications. Consult manufacturer cross-reference guides for other compatible bridge rectifier options.
