S3KBH

Single Diodes Overview

The S3KBH is a general-purpose standard recovery diode manufactured by Taiwan Semiconductor Corporation. It features a maximum DC reverse voltage (Vr) of 800 V and an average forward rectified current (Io) of 3 A. The component utilizes the DO-214AA (SMB) surface-mount package. Key electrical parameters include a maximum forward voltage (Vf) of 1.15 V at 3 A, a maximum reverse leakage current (Ir) of 10 µA at 800 V, and a junction temperature range of -55°C to 150°C.

Single Diodes Feature Summary

• High voltage blocking capability suitable for demanding power applications

Single Diodes Procurement Notes

Verify the specific suffix 'BH' against official datasheets to confirm packaging and marking details. Ensure compatibility with RoHS3 and REACH regulations as per manufacturer specifications. Confirm the DO-214AA footprint matches the target PCB layout before procurement.

Single Diodes Selection Notes

Select this component when an 800 V reverse voltage rating is required for 3 A continuous current applications. The standard recovery characteristic distinguishes it from fast-recovery or Schottky alternatives. Evaluate thermal management requirements based on the specified junction temperature limits.
