USD545

Single Diodes Overview

The USD545 is a single Schottky rectifier diode manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 45V and an average forward rectified current rating of 75A. The device utilizes a rugged DO-5 (DO-203AB) stud mount package, suitable for high-power applications. Key electrical characteristics include a low forward voltage drop of 0.6V at 60A and 125°C, with a low reverse leakage current of less than 50mA at rated VR and 125°C.

Single Diodes Feature Summary

• Very low forward voltage drop to minimize conduction losses
• Low recovered charge for improved switching efficiency
• Rugged DO-5 stud mount package design for thermal stability

Single Diodes Applications

• High-current DC power supply rectification
• Industrial motor drive freewheeling circuits
• Battery charging systems requiring low loss

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and mounting configuration. Confirm that the DO-5 stud mount interface matches your heatsink requirements. Check for RoHS compliance status if environmental regulations apply to your assembly process.

Single Diodes Selection Notes

Select this component when high current handling capacity above 75A is not required but low forward voltage is critical. Ensure the operating junction temperature remains within specified limits given the 45V reverse voltage rating. Verify thermal management solutions are adequate for the expected ambient conditions and load cycles.

Single Diodes Part Context

This part belongs to Microchip Technology's single Schottky diode lineup designed for power rectification. The USD545 specifically targets applications needing robust performance in a stud-mount form factor. It complements other devices in the series offering different voltage or current ratings while maintaining similar low-loss characteristics.

Single Diodes Replacement Considerations

Check for direct substitutes such as the USD545E3 variant which may offer specific compliance attributes. Compare pin compatibility and thermal resistance values before substituting with generic equivalents from other manufacturers.
