181NQ045

Overview

The Vishay 181NQ045 is a high-current Schottky rectifier module in the Half-Pak series, rated for 45 V DC reverse voltage and 180 A average forward current. It features a maximum forward voltage drop of 0.66 V at 180 A and supports junction temperatures up to 175 °C. The device offers a peak non-repetitive surge current of 22,000 A and includes avalanche energy ratings. Electrical characteristics include a maximum reverse leakage current of 15 mA at 25 °C and a typical series inductance of 6.0 nH.

Feature Summary

Proprietary barrier technology enables reliable operation at elevated junction temperatures up to 175 °C.
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 suffix (R) if polarity inversion is required, as standard and reversed pinout versions exist within the same series. Confirm that the mounting surface is smooth and greased to achieve the specified thermal resistance values. Ensure torque specifications are strictly followed during installation to maintain mechanical integrity and electrical performance.

Selection Notes

Select this component for applications requiring high current handling and low conduction losses. The Half-Pak package allows for easier mounting and lower profile compared to parallel DO-5 configurations. Consider the thermal resistance and case temperature limits when designing heatsinking solutions for continuous operation.

Part Context

This part belongs to the 181NQ...R Series of high current Schottky rectifiers from Vishay General Semiconductor - Diodes Division. The series is designed to replace three parallel DO-5 diodes, offering a more compact and efficient solution for high-power applications while maintaining robust thermal and electrical performance.
