STPS40M100CT

Diode Arrays Overview

The STPS40M100CT is a dual common cathade Schottky rectifier manufactured by STMicroelectronics. It features a 100 V repetitive peak reverse voltage and a 20 A average forward current per diode, totaling 40 A in the dual configuration. The device utilizes a TO-220AB package for through-hole mounting. Key electrical characteristics include a low forward voltage drop of approximately 850 mV at 20 A and a maximum non-repetitive peak forward surge current of 360 A. The component operates within a junction temperature range of -65 °C to +175 °C.

Diode Arrays Procurement Notes

Verify the specific suffix against official STMicroelectronics documentation to confirm exact pinout and thermal specifications. Ensure the procurement channel provides genuine components with traceable lot codes. Cross-reference the datasheet revision date to guarantee compatibility with current design standards and environmental compliance requirements such as RoHS directives.

Diode Arrays Selection Notes

Select this component when designing systems requiring high current handling at low voltage drops. The dual common cathode topology simplifies circuit layout for bridge-less PFC or synchronous rectification topologies. Evaluate thermal management needs based on the TO-220AB package's thermal resistance characteristics under expected load conditions.

Diode Arrays Part Context

This part belongs to the STPS40M series of Power Schottky Rectifiers from STMicroelectronics. The series is engineered for medium to high power density applications. The 'CT' designation indicates the dual common cathode configuration, distinguishing it from single diode variants within the same voltage and current rating family.

Diode Arrays Replacement Considerations

Direct replacements must match the 100 V / 40 A (dual) rating and TO-220AB package. Verify equivalent forward voltage and leakage current specs. Check for identical avalanche ratings and thermal performance characteristics before substitution.
