STPS40SM100CT

Diode Arrays Overview

The STPS40SM100CT is a dual low leakage power Schottky rectifier from STMicroelectronics, rated at 100 V and 40 A. It features a common cathode configuration in a TO-220AB package. The device is optimized for high-frequency switch mode power supplies (SMPS) and DC-to-DC converters. Key electrical characteristics include a maximum forward voltage of 940 mV at 20 A per diode and a low reverse leakage current of 3.5 µA at 100 V. It operates within a junction temperature range of -65 °C to +175 °C and supports a forward surge current of 300 A.

Diode Arrays Feature Summary

• Low leakage current for improved efficiency
• Negligible switching losses enabling high-frequency operation
• Specified avalanche capability for ruggedness

Diode Arrays Applications

• High frequency switch mode power supplies
• Free-wheeling applications
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's official datasheet to confirm the exact packaging type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to confirm current production status and availability.

Diode Arrays Selection Notes

Select this component for designs requiring low reverse leakage and high current handling in a through-hole package. The trade-off between forward voltage drop and leakage current makes it suitable for both low and high load conditions. Consider thermal management solutions given the 175 °C maximum junction temperature rating.

Diode Arrays Part Context
