80CNQ040A

Overview

The Vishay VS-80CNQ040A is a center tap Schottky rectifier module rated for 40 A average forward current per leg and a maximum DC reverse voltage of 40 V. It utilizes the D-61-8 through-hole package with a base common cathode configuration. The device supports junction temperatures up to 150 °C, features a low forward voltage drop of 0.47 V at 40 A and 125 °C, and offers high surge current capability.

Feature Summary

• Center tap dual anode common cathode configuration
• High purity epoxy encapsulation for mechanical strength
• Guard ring design for enhanced ruggedness
• Optimized barrier technology for reliable operation

Applications

• Switching power supplies
• DC-DC converters
• Freewheeling diodes
• Reverse battery protection circuits

Procurement Notes

Verify the specific package variant (D-61-8, D-61-8-SM, or D-61-8-SL) required for your assembly process. Confirm RoHS compliance status based on the PbF suffix designation. Ensure thermal management solutions account for the specified thermal resistance values under your operating conditions.

Selection Notes

Select this component for applications requiring high current handling in a compact footprint. Evaluate thermal performance against the maximum junction temperature limit of 150 °C. Consider the low forward voltage characteristics for efficiency optimization in high-frequency switching environments.

Part Context

This part belongs to the VS-80CNQ...A PbF Series, representing Vishay's New Generation 3 D-61 Package line. It is designed as a high-power Schottky rectifier module intended for industrial level qualification and robust performance in demanding power electronics applications.

Replacement Considerations

Consult official documentation for direct substitutes within the same series, such as the VS-80CNQ035A or VS-80CNQ045A, which share identical packaging and electrical configurations but differ in reverse voltage ratings.
