SS315FSH

Single Diodes Overview

The SS315FSH is a surface-mount Schottky barrier rectifier manufactured by Taiwan Semiconductor. It features a 150 V reverse voltage rating and a 3 A average forward current capability. The device utilizes an SOD-128FL package, designed for low-profile applications requiring efficient heat dissipation. It is qualified to the AEC-Q101 standard for automotive reliability. Key electrical characteristics include a maximum forward voltage of 0.64 V at 3 A and a very low reverse leakage current of 1 mA at rated voltage. The component supports a maximum operating junction temperature of 175 °C.

Single Diodes Feature Summary

• Schottky barrier construction ensures negligible switching losses and extremely fast switching speeds.
• AEC-Q101 qualification guarantees suitability for demanding automotive electronic environments.
• Low profile SOD-128FL package facilitates space-saving PCB layouts with wettable flanks.

Single Diodes Applications

• Free-wheeling diodes in low-voltage high-frequency DC-to-DC converters
• Polarity protection circuits in automotive systems
• Power supplies for infotainment and instrument clusters

Single Diodes Procurement Notes

Verify the specific suffix 'FSH' against the official Taiwan Semiconductor datasheet to confirm package type and tape-and-reel specifications. Ensure the procurement channel provides traceability documentation required for AEC-Q101 components. Confirm that the received parts match the manufacturing date codes and lot numbers specified in the purchase order to maintain supply chain integrity.

Single Diodes Selection Notes

Select this component when designing circuits requiring high efficiency at moderate currents up to 3 A. The low forward voltage drop minimizes conduction losses compared to standard silicon rectifiers. Consider the thermal resistance of the SOD-128FL package relative to the expected ambient temperature and power dissipation. Verify that the 150 V reverse voltage rating exceeds the peak inverse voltage present in the target application circuit.

Single Diodes Part Context

This part belongs to the SSxL series of automotive-grade Schottky rectifiers from Taiwan Semiconductor. These devices are engineered to replace bulkier through-hole rectifiers in modern compact electronics. The series offers various voltage and current ratings to cover diverse power management needs in consumer and industrial sectors while maintaining strict automotive quality standards.

Single Diodes Replacement Considerations

Direct replacements must match the 3 A current, 150 V voltage, and SOD-128FL package. Verify pinout compatibility and thermal characteristics before substitution.
