183NQ100

Overview

The Vishay 183NQ100 is a high-current Schottky rectifier module in the Half-Pak case style. It features a maximum DC reverse voltage of 100 V and an average forward current rating of 180 A with a rectangular waveform. The device supports junction temperatures from -55 °C to 175 °C, with a maximum thermal resistance of 0.30 °C/W from junction to case. Electrical characteristics include a peak one-cycle non-repetitive surge current of 22,000 A at 5 µs and a typical series inductance of 6.0 nH.

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, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance
• Guard ring design enhances ruggedness and long-term reliability

Applications

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

Procurement Notes

Verify the specific suffix designation against the manufacturer datasheet to confirm terminal polarity configuration. The standard 183NQ100 variant utilizes a Lug Terminal Anode and Base Cathode arrangement, whereas the 183NQ100R variant reverses this orientation. Ensure mounting torque specifications are strictly adhered to during installation to maintain thermal interface integrity.

Selection Notes

Select this component for applications requiring high-frequency operation and low forward voltage drop. The Half-Pak package offers a lower profile and easier mounting compared to parallel DO-5 configurations. Verify that the system can accommodate the specified 22,000 A surge current capability and that the heatsinking strategy maintains the junction temperature within the 175 °C limit under continuous load conditions.

Part Context

This component belongs to the 183NQ series of high current Schottky rectifier modules manufactured by Vishay General Semiconductor - Diodes Division. The series includes variants with different reverse voltage ratings, specifically 80 V and 90 V options alongside the 100 V model. These modules are designed as industrial-level replacements for multiple discrete diodes connected in parallel.

Replacement Considerations

The datasheet indicates the module replaces three parallel DO-5 diodes.
