125SPC015A

Overview

The 125SPC015A is a Schottky rectifying diode manufactured by SMC Diode Solutions, designed for surface-mount applications in the SPD-3A package. It features a maximum repetitive reverse voltage of 15V and an average forward current rating of 120A. The device exhibits a maximum forward voltage drop of 410mV at 120A and a reverse leakage current of 40mA at 15V. It supports junction temperatures up to 125°C and is available in lead-free, RoHS-compliant configurations.

Feature Summary

• Schottky barrier technology for low forward voltage drop
• High current capacity suitable for power conversion
• Surface-mount packaging for automated assembly

Applications

• DC motor control and drives
• Battery chargers
• Welders
• Power converters
• Reverse polarity protection

Procurement Notes

Verify RoHS compliance status as sources indicate conflicting information regarding lead-free certification. Confirm package type SPD-3A matches design requirements. Check for active lifecycle status before procurement. Ensure thermal management supports 125°C junction temperature operation.

Selection Notes

Select this component when low forward voltage drop is critical for efficiency in high-current circuits. The 15V rating suits low-voltage DC systems. Consider the SPD-3A package size for board space constraints. Verify thermal dissipation capabilities for continuous 120A operation.

Part Context

This part belongs to the SMC Diode Solutions Schottky rectifier series, specifically engineered for high-power density applications. The SPD-3A package offers a compact form factor compared to traditional through-hole alternatives like DO-5, facilitating easier mounting and lower profile designs in modern electronic assemblies.

Replacement Considerations

The datasheet for the related 125NQ015/R-1 indicates that similar Half-Pak modules can replace three parallel DO-5 diodes. Verify electrical compatibility with existing circuit designs before substituting.
