KBL08-M3/A

Overview

The KBL08-M3/A is a single-phase standard bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 8 A average rectified current (Io) and a maximum repetitive peak reverse voltage (Vr) of 800 V. The forward voltage drop (Vf) is specified at 1.25 V when conducting 8 A, with a maximum reverse leakage current of 5 µA at the rated voltage. Designed for through-hole mounting in the KBL package, this component operates within a junction temperature range of -55°C to +150°C. It complies with RoHS directives and is marked as halogen-free.

Feature Summary

• High-voltage capability suitable for demanding power supply applications
• Halogen-free construction compliant with environmental standards
• Robust thermal performance supporting high junction temperatures

Applications

• AC-DC power supply circuits
• Battery chargers
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical ratings. Ensure the ordering part number matches the required voltage and current specifications for the target design. Confirm compliance requirements such as RoHS status directly from the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component for designs requiring 800 V blocking voltage and 8 A continuous current in a compact through-hole format. Compare Vf characteristics against alternative packages if thermal management is constrained. Verify that the KBL footprint aligns with the PCB layout constraints and that the operating temperature range meets the system's environmental demands.

Part Context

This device belongs to the KBL series of bridge rectifiers, which are widely used in general-purpose power conversion. The M3 suffix indicates lead-free termination and halogen-free material composition, adhering to modern environmental regulations. The KBL package provides a balance between current handling capacity and physical size for board-mounted applications.

Replacement Considerations

Cross-reference with other manufacturers offering 800 V, 8 A bridge rectifiers in the KBL or equivalent SIP-4 package. Verify that substitute components match the forward voltage drop and reverse leakage specifications to ensure circuit performance consistency.
