129NQ135

Overview

The Vishay 129NQ135 is a high-current Schottky rectifier module in the Half-Pak series, rated for 135 V DC reverse voltage and 120 A average forward current. It features a maximum forward voltage drop of 1.07 V at 120 A and operates reliably up to a junction temperature of 175°C. The device utilizes proprietary barrier technology to minimize reverse leakage at elevated temperatures.

Feature Summary

Optimized low reverse leakage at high temperatures using proprietary barrier technology
Reliable operation up to 175°C junction temperature
High purity, high temperature epoxy encapsulation for mechanical strength and moisture resistance
Guard ring design for enhanced ruggedness and long-term reliability

Applications

Switching power supplies
Converters
Free-wheeling diodes
Reverse battery protection

Procurement Notes

Verify the specific suffix (R) against the datasheet to confirm terminal polarity configuration, as lug and base assignments differ between standard and reversed variants. Confirm thermal interface requirements, noting the typical case-to-heatsink resistance assumes a smooth, greased mounting surface. Ensure mounting torque specifications are strictly adhered to during installation.

Selection Notes

Select this component for applications requiring high surge capability and low forward voltage drop. The 129NQ135 supports a peak non-repetitive surge current of 10,000 A for short pulses. Consider the Half-Pak package profile if space constraints exist relative to parallel DO-5 configurations. Verify thermal management capabilities align with the specified maximum junction temperature range.

Part Context

This part belongs to the 129NQ... (R) series of high current Schottky rectifiers designed to replace two parallel DO-5 diodes. The Half-Pak module offers a lower profile and easier mounting compared to traditional discrete setups. The series includes variants with different reverse voltage ratings, such as the 129NQ150.
