Overview
The Vishay 160CMQ040 is a Schottky rectifier module rated for 160 A average forward current and 40 V maximum DC reverse voltage. It features an isolated center-tap configuration in a TO-249AA package, optimized for low forward voltage drop of 0.86 V at full load. The device supports junction temperatures up to 150°C and offers high surge capability with a non-repetitive peak current of 6400 A.
Feature Summary
- Isolated center-tap design for enhanced thermal management
- Very low forward voltage drop for improved efficiency
- High frequency operation capability
- Guard ring structure for long-term reliability
Applications
- Switching power supplies
- DC-DC converters
- Free-wheeling diodes
- Reverse battery protection circuits
Procurement Notes
Verify the specific suffix (e.g., 040) matches the required voltage rating during procurement. Confirm that the TO-249AA package dimensions align with the target heatsink interface. Ensure mounting torque specifications are strictly followed to maintain thermal performance and mechanical integrity.
Selection Notes
Select this component when high current handling and low conduction losses are critical. The isolated case allows direct mounting to a heatsink without electrical insulation requirements. Consider the thermal resistance values to ensure adequate cooling for the intended duty cycle and ambient temperature conditions.
Part Context
This part belongs to the 160CMQ series of Schottky rectifiers from International Rectifier, now part of Infineon Technologies. The series utilizes proprietary barrier technology to achieve reliable operation at elevated junction temperatures while maintaining low leakage currents typical of Schottky devices.
