S40M

Single Diodes Overview

The S40M is a silicon standard recovery rectifier diode manufactured by GeneSiC Semiconductor. It features a DO-5 (DO-203AB) stud mount package with the stud configured as the cathode terminal. The device supports a repetitive peak reverse voltage of 1000 V and a continuous forward current rating of 40 A. Electrical characteristics include a maximum forward voltage of 1.1 V at 40 A and a reverse leakage current of 10 mA at 100 V. Thermal resistance from junction to case is specified at 9 °C/W, enabling operation within a temperature range of -55 °C to 150 °C.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Stud mount configuration with standardized mechanical dimensions
• Standard polarity design where the base stud serves as the cathode

Single Diodes Procurement Notes

Verify the specific suffix designation against official documentation to confirm the exact voltage rating and lead configuration. Confirm that the procurement channel provides original manufacturer packaging to ensure component authenticity and traceability. Check for any regional distribution restrictions or RoHS compliance details prior to finalizing orders.

Single Diodes Selection Notes

Select this component when a robust silicon standard recovery diode is required for high-current applications. The DO-5 package facilitates efficient heat dissipation through direct mounting to a heatsink. Ensure the circuit design accommodates the specified thermal resistance and operating temperature limits for reliable long-term performance.

Single Diodes Part Context

This part belongs to the S40K thru S40QR series of silicon standard recovery diodes. The series offers various voltage ratings ranging from 800 V to 1200 V while maintaining a consistent 40 A current capacity. All variants share the same physical DO-5 package footprint and mounting interface for interchangeability.

Single Diodes Replacement Considerations

Compatible substitutes within the same series include S40K and S40Q. Verify that replacement parts match the 1000 V reverse voltage requirement and maintain identical thermal and electrical specifications.
