SS34B-HF

Single Diodes Overview

The SS34B-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SMBF (DO-214AA) package. Key electrical parameters include a maximum average forward rectified current of 3 A and a maximum repetitive peak reverse voltage of 40 V. The device exhibits a typical forward voltage drop of 550 mV at rated current and a maximum reverse leakage current of 500 uA. It supports a high surge forward current of 80 A and operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific suffix against official manufacturer documentation, as variations may exist between SS34B and SS34BF-HF designations. Confirm RoHS compliance status and exact package dimensions prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target circuit environment.

Single Diodes Selection Notes

Select this component for designs requiring efficient rectification in compact surface-mount layouts. The 3 A current rating and 40 V breakdown voltage suit general-purpose low-voltage DC-DC conversion. Consider the 550 mV forward voltage drop when calculating total system power dissipation and thermal management requirements.

Single Diodes Part Context

This part belongs to the SS3x series of Schottky barrier rectifiers from Comchip Technology. These devices are silicon-based components optimized for high-speed switching and low forward voltage characteristics. The SMBF package provides a standardized footprint compatible with automated assembly processes commonly used in modern electronics manufacturing.

Single Diodes Replacement Considerations

Compatible substitutes include SS34B-F, SS34B-LFR, and SS34B-Q from other manufacturers offering identical 3 A/40 V SMBF specifications. Verify pinout compatibility and thermal resistance values before substitution.
