123NQ100

Overview

The Vishay 123NQ100 is a high-current Schottky rectifier module in the D-67 Half-Pak package. It features a maximum average forward current of 120 A and a peak reverse repetitive voltage of 100 V. The device supports junction temperatures from -55°C to 175°C with a thermal resistance of 0.40 °C/W. Key electrical parameters include a maximum forward voltage drop of 0.91 V at 120 A, a peak non-repetitive surge current of 16,000 A, and a maximum reverse leakage current of 3 mA at 25°C.

Feature Summary

• Optimized for low reverse leakage current at elevated temperatures
• Proprietary barrier technology enables reliable operation up to 175°C junction temperature
• High purity epoxy encapsulation provides enhanced mechanical strength and moisture resistance
• Guard ring design improves ruggedness and long-term reliability

Applications

• Switching power supplies
• Converters
• Free-wheeling diodes
• Reverse battery protection

Procurement Notes

Verify the specific suffix (e.g., PBF) against the manufacturer's datasheet to confirm RoHS compliance status. Ensure the mounting surface is smooth and greased to achieve the typical case-to-heatsink thermal resistance value of 0.15 °C/W. Confirm that the application circuit respects the absolute maximum ratings for avalanche energy and repetitive avalanche current if inductive loads are present.

Selection Notes

Select this component when high current handling and low forward voltage drop are required in a compact panel-mount form factor. The D-67 Half-Pak module replaces two parallel DO-5 packages, offering a lower profile and easier mounting. Verify that the system can accommodate the specified minimum and maximum terminal torque values to ensure secure connections without damaging the module.

Part Context

The 123NQ100 belongs to the 123NQ... (R) series of high current Schottky rectifiers. This series utilizes unique high-power Half-Pak modules designed for industrial level applications. The product line is optimized for high-frequency operation and offers superior performance compared to traditional discrete parallel configurations.
