182NQ030

Overview

The Vishay 182NQ030 is a high-current Schottky rectifier module rated for 30 V DC reverse voltage and 180 A average forward current. It utilizes Half-Pak packaging with a maximum junction temperature of 150°C. Key electrical parameters include a typical forward voltage drop of 0.41 V at 180 A, a peak non-repetitive surge current of 30,000 A (5 µs), and a maximum thermal resistance from junction to case of 0.30 °C/W.

Feature Summary

• Optimized proprietary barrier technology ensures reliable operation up to 150°C junction temperature.
• Half-Pak module design offers lower profile and easier mounting compared to parallel DO-5 configurations.
• High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance.
• Guard ring structure enhances ruggedness and long-term reliability.

Applications

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

Procurement Notes

Verify the specific manufacturer source, as documentation references both Infineon and Vishay branding. Confirm package dimensions and mounting torque specifications against the latest datasheet revision. Ensure thermal interface material compatibility with the specified case-to-heatsink thermal resistance requirements for proper heat dissipation.

Selection Notes

Select this component for applications requiring high current handling in a compact form factor. The low forward voltage drop minimizes conduction losses, while the 150°C rating supports high-temperature environments. Evaluate thermal management needs based on the 0.30 °C/W junction-to-case resistance to maintain safe operating temperatures under load.

Part Context
