160CMQ045

Overview

The Vishay 160CMQ045 is a Schottky rectifier module rated for 45 V DC reverse voltage and 160 A average forward current. It features a center tap configuration with an isolated heatsink in a TO-249AA package. The device exhibits a maximum forward voltage drop of 0.86 V at 160 A and supports junction temperatures up to 150°C. Key electrical parameters include a peak surge current of 6400 A, a maximum reverse leakage current of 200 mA at 125°C, and a typical series inductance of 8.0 nH per leg.

Feature Summary

• Center tap module design with an electrically isolated heatsink
• Optimized for very low forward voltage drop and high frequency operation
• Guard ring structure provides enhanced ruggedness and long term reliability
• High purity, high temperature epoxy encapsulation for mechanical strength

Applications

• Switching power supplies
• Converters
• Free-wheeling diodes
• Reverse battery protection

Procurement Notes

Verify the specific suffix code against official documentation to confirm the exact reverse voltage rating, as the series spans multiple voltage options. Confirm thermal interface requirements and mounting torque specifications (40 to 58 kg-cm) during integration. Ensure the procurement source provides original manufacturer datasheets rather than third-party summaries to validate absolute maximum ratings and thermal characteristics.

Selection Notes

Select this component when high current handling and low conduction losses are required in a compact form factor. The isolated center tap simplifies thermal management by allowing direct heatsink attachment without electrical isolation components. Evaluate the 150°C junction temperature capability against ambient conditions to determine necessary heatsinking. Consider the 8.0 nH series inductance for high-speed switching applications where parasitic effects impact performance.
