VS-STPS40L40CW-N3

Diode Arrays Overview

The VS-STPS40L40CW-N3 is a dual center tap Schottky rectifier from Vishay Semiconductors, packaged in TO-247AC. It features two independent anodes with a common cathode configuration. The device supports a maximum average forward current of 40 A and a repetitive peak reverse voltage of 40 V. Key electrical parameters include a typical forward voltage drop of 0.43 V at 20 A and 125 °C, and a maximum non-repetitive surge current of 3500 A. It operates within a junction temperature range of -55 °C to 150 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm environmental compliance status. The -N3 suffix indicates halogen-free, RoHS compliant, and totally lead-free construction. Confirm package dimensions match the TO-247AC outline drawing before integration into PCB layouts or heatsink assemblies.

Diode Arrays Selection Notes

Select this component when designing systems requiring high current handling with minimal forward voltage drop. Ensure the application voltage does not exceed the 40 V rating. Consider thermal management requirements based on the specified junction-to-case thermal resistance values for continuous operation.

Diode Arrays Part Context

This part belongs to the STPS series of Schottky barrier rectifiers designed by Vishay. The '40' designation indicates a 40 A current rating, while the second '40' specifies the 40 V reverse voltage capability. The 'L' denotes the low forward voltage variant optimized for efficiency.

Diode Arrays Replacement Considerations

Cross-reference with other Vishay STPS series parts sharing the TO-247AC package and similar electrical ratings. Verify pinout compatibility and thermal characteristics before substituting.
