SS54FSH

Single Diodes Overview

The SS54FSH is a surface mount Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a DO-214AC (SMC) package and provides an average forward current of 5 A with a maximum repetitive peak reverse voltage of 40 V. The device utilizes metal-to-silicon construction for majority carrier conduction, ensuring low forward voltage drop and high surge current capability. It operates within a junction temperature range of -55°C to +150°C and meets UL 94V-0 flammability standards for its molded plastic case.

Single Diodes Feature Summary

• Metal-to-silicon rectifier structure utilizing majority carrier conduction
• Low forward voltage drop for improved efficiency
• High surge current capability for robust performance
• Molded plastic case with UL 94V-0 flame retardant rating

Single Diodes Applications

• Free wheeling diodes in inductive circuits
• Polarity protection in power supply inputs
• Reverse battery protection systems

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as the suffix 'FSH' may indicate specific packaging or material compliance variations compared to standard industry equivalents. Confirm RoHS compliance status directly with the supplier documentation. Ensure the DO-214AC footprint matches the target PCB layout requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for applications requiring high current handling in a compact surface mount form factor. The 40 V reverse voltage rating suits low-voltage DC systems. Consider the thermal management requirements associated with 5 A continuous operation. Verify that the low forward voltage characteristics align with the system's efficiency targets.

Single Diodes Part Context

This part belongs to the SS series of surface mount Schottky barrier rectifiers from Taiwan Semiconductor Corporation. These devices are designed for general-purpose rectification in consumer electronics and industrial equipment. The SMC package allows for higher current capacity compared to smaller SMA or SMB packages while maintaining surface mount compatibility.

Single Diodes Replacement Considerations

Standard SS54 parts from other manufacturers serve as direct functional substitutes provided they utilize the DO-214AC package and meet the 5 A / 40 V specifications.
