Overview
The Vishay General Semiconductor - Diodes Division 120NQ040 is a high-current Schottky rectifier module within the 120NQ...(R) series. It features a maximum DC reverse voltage of 40 V and an average forward current rating of 120 A at a case temperature of 106°C. The device utilizes proprietary barrier technology to achieve a low forward voltage drop of 0.57 V at 120 A and operates reliably up to a junction temperature of 150°C. Packaged in a D-67 Half-Pak module, it offers enhanced mechanical strength and moisture resistance through high-purity epoxy encapsulation.
Feature Summary
- Proprietary barrier technology enables reliable operation up to 150°C junction temperature with very low forward voltage drop.
- High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance.
- Guard ring design ensures enhanced ruggedness and long-term reliability under high-stress conditions.
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. Ensure thermal management solutions align with the specified thermal resistance values for the intended operating environment. Confirm that mounting torque specifications are strictly followed during installation to maintain structural integrity and electrical performance.
Selection Notes
Select this component for applications requiring high surge current handling and low forward voltage drop at elevated temperatures. The D-67 Half-Pak module is suitable for designs needing easier mounting and lower profile compared to parallel DO-5 configurations. Consider the 150°C junction temperature capability for robust industrial-level performance.
Part Context
The 120NQ040 belongs to the 120NQ...(R) series of high current Schottky rectifier modules manufactured by Vishay General Semiconductor - Diodes Division. This series is optimized for moderate leakage and very low forward voltage drop, making it distinct from standard discrete diodes. The module format replaces two parallel DO-5s, offering a more compact and efficient solution for high-power rectification tasks.
Replacement Considerations
The datasheet indicates the 120NQ040 replaces two parallel DO-5 diodes. Verify compatibility with existing circuit layouts when substituting discrete components with this module format.
