89CNQ150A

Overview

The Vishay 89CNQ150A is a center-tap Schottky rectifier module rated for 150 V reverse voltage and 40 A average forward current per leg. It utilizes proprietary barrier technology to achieve low forward voltage drop, specified at 0.69 V at 40 A and 125 °C junction temperature. The device supports operation up to 175 °C junction temperature and features high purity epoxy encapsulation for mechanical strength. Electrical characteristics include a typical reverse leakage of 1.5 mA at 25 °C and a maximum junction-to-case thermal resistance of 0.85 °C/W per leg.

Feature Summary

Center tap configuration optimized for low forward voltage drop
Proprietary barrier technology enabling reliable 175 °C operation
High purity, high temperature epoxy encapsulation for moisture resistance
Guard ring design for enhanced ruggedness and long term reliability

Applications

Switching power supplies
Converters
Free wheeling diodes
Reverse battery protection

Procurement Notes

Verify the specific package variant required, as the base model number corresponds to multiple physical outlines including D61-8-SM, D61-8-SL, and standard D61-8. Confirm that the manufacturer designation aligns with the original International Rectifier specifications now under Vishay General Semiconductor. Ensure sourcing channels provide documentation confirming the component meets industrial level qualification standards.

Selection Notes

Select this component when designing circuits requiring a center-tapped Schottky rectifier with high surge capability. The 4300 A peak non-repetitive surge rating supports robust performance in inductive load switching. Consider the 0.85 °C/W junction-to-case thermal resistance for heatsink calculations. Verify that the operating environment remains within the -55 °C to 175 °C junction temperature range to maintain specified electrical parameters.

Part Context

This part belongs to the 89CNQ...A series of center tap Schottky rectifiers manufactured by Vishay General Semiconductor - Diodes Division. The series includes variants with different reverse voltage ratings, such as the 89CNQ135A. These modules are designed for industrial applications requiring high current handling and high temperature stability in compact packages.
