KBL04-M3/P

Overview

The KBL04-M3/P is a bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes silicon planar technology and features the e3 lead-free terminal finish. The component is housed in a plastic case with an epoxy molding compound rated UL Flammability Classification 94V-0. Key electrical parameters include a maximum average forward rectified current of 1.0 A at 75°C, a repetitive peak reverse voltage of 40 V, and a non-repetitive peak forward surge current of 25 A. The device operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Utilizes planar metallurgy for robust performance
• Features low forward voltage drop characteristics
• Equipped with high surge current capability
• Complies with RoHS Directive 2002/95/EC

Applications

• General purpose rectification in power supplies
• Adapters and chargers

Procurement Notes

Verify the specific suffix P against official Vishay documentation to confirm package type variations. Ensure compliance requirements match project specifications. Confirm thermal management needs align with the 1.0 A rating at elevated temperatures. Validate that the 40 V reverse voltage meets circuit safety margins. Check datasheet for precise mounting torque and soldering profiles.

Selection Notes

Select this component when a compact bridge rectifier is required for low-voltage applications. The 40 V rating suits circuits with minimal voltage spikes. Consider the 1.0 A current limit for small load requirements. Evaluate thermal dissipation capabilities if operating near the 75°C derating point. Compare physical dimensions against PCB layout constraints.

Part Context

This part belongs to the KBL series of bridge rectifiers from Vishay. The series offers various voltage ratings and current capacities. The M3 designation indicates lead-free terminals and halogen-free materials. The KBL package provides a compact solution for surface mount or through-hole integration depending on the specific variant.

Replacement Considerations

Cross-reference with other Vishay KBL series parts for different voltage ratings. Verify pinout compatibility before substituting. Ensure equivalent current and surge ratings are maintained. Check mechanical dimensions for board fitment.
