Overview
The Vishay 89CNQ150ASL is a center-tap Schottky rectifier module in the GenIII D-61 package. It features two legs with a maximum DC reverse voltage of 150 V and an average forward current of 40 A per leg (80 A total). The device operates up to a junction temperature of 175 °C, with a typical forward voltage drop of 0.78 V at 80 A. Key electrical parameters include a peak surge current of 4300 A and a 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 operation up to 175°C junction temperature
- High purity, high temperature epoxy encapsulation for mechanical strength and 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 suffix 'ASL' against the datasheet outline table to confirm the lead type matches the intended PCB footprint. Confirm that the manufacturer documentation aligns with the requested brand, as historical records may reference International Rectifier for this series. Ensure the component meets industrial level qualification standards required for the target application environment.
Selection Notes
Select this module when high frequency operation and low forward voltage drop are critical for efficiency. The 175 °C junction temperature rating allows for robust performance in thermally constrained environments. Consider the D-61 package dimensions and mounting torque requirements during the mechanical design phase to ensure proper heatsinking and structural integrity.
Part Context
This component belongs to the 89CNQ...A Series, which utilizes the New GenIII D-61 Package. This family includes variants such as 89CNQ135A and 89CNQ150A, distinguished primarily by their reverse voltage ratings. The series is designed for high current applications requiring small footprint and high reliability in industrial settings.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the same series or package family. Verify that any substitute maintains the 150 V reverse voltage rating and 40 A per leg current capacity. Ensure the replacement supports the required 175 °C junction temperature operation.
