Overview
The Vishay 120NQ035 is a high-current Schottky rectifier module in the D-67 Half-Pak case style. It features a maximum DC reverse voltage of 35 V and an average forward current rating of 120 A at a case temperature of 106 °C. The device supports junction temperatures from -55 to 150 °C with a thermal resistance of 0.40 °C/W. Electrical characteristics include a maximum forward voltage drop of 0.57 V at 120 A, a peak non-repetitive surge current of 29,000 A, and a typical series inductance of 7.0 nH.
Feature Summary
- Proprietary barrier technology enables reliable operation up to 150 °C junction temperature.
- Optimized for very low forward voltage drop with moderate leakage current.
- High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance.
- Guard ring design ensures enhanced ruggedness and long-term reliability.
Applications
- Switching power supplies
- Converters
- Free-wheeling diodes
- Reverse battery protection
Procurement Notes
Verify the specific part number suffix against official documentation to confirm exact voltage ratings and package variations. Confirm that the component meets industrial level qualification standards required for the intended application environment. Ensure mounting hardware complies with specified torque limits to maintain thermal interface integrity.
Selection Notes
Select this component for applications requiring high current handling and low forward voltage drop. Evaluate thermal management requirements based on the 0.40 °C/W junction-to-case resistance. Consider the D-67 Half-Pak form factor for easier mounting compared to parallel DO-5 configurations.
Part Context
This component belongs to the 120NQ...(R) series of high current Schottky rectifier modules manufactured by Vishay General Semiconductor - Diodes Division. The series utilizes unique high power packaging designed to replace two parallel DO-5 diodes while offering a lower profile.
Replacement Considerations
The datasheet indicates the module replaces two parallel DO-5 diodes. Verify compatibility with existing circuit layouts when substituting parallel discrete diode arrangements.
