80CNQ045A

Overview

The Vishay VS-80CNQ045A is a center tap Schottky rectifier module featuring two anodes and a common cathode configuration. It provides a maximum average forward current of 80 A per device (40 A per leg) and a maximum DC reverse voltage of 45 V. The component utilizes the D-61-8 through-hole package, operates up to a junction temperature of 150 °C, and exhibits a typical forward voltage drop of 0.66 V at 80 A and 125 °C.

Feature Summary

• Center tap dual anode common cathode architecture
• High frequency operation with very low forward voltage drop
• Guard ring design for enhanced ruggedness and long term reliability
• High purity epoxy encapsulation for mechanical strength and moisture resistance

Applications

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

Procurement Notes

Verify the specific suffix against the datasheet ordering table to confirm the package style. The 'A' suffix indicates the D-61-8 through-hole variant. Confirm RoHS compliance status as standard production may differ from PbF versions. Validate thermal mounting requirements and torque specifications before integration.

Selection Notes

Select this component when a center tap topology is required for high current applications. Ensure the circuit can accommodate the 45 V reverse voltage rating. Verify that the thermal management system supports the specified junction temperature range and thermal resistance values under the expected duty cycle conditions.

Part Context

This part belongs to the VS-80CNQ...A PbF Series, which includes variants with different reverse voltage ratings such as 35 V and 40 V. All series members share the same 80 A current rating and utilize the New Generation 3 D-61 package technology designed for industrial level qualification and high reliability.
