120NQ045R

Overview

The Vishay 120NQ045R is a high-current Schottky rectifier module rated for 120 A average forward current and 45 V maximum DC reverse voltage. It utilizes proprietary barrier technology to achieve very low forward voltage drop, specified at 0.57 V at 120 A. The device operates reliably up to a junction temperature of 150 °C and features a D-67 Half-Pak case style designed for base mounting. Key electrical characteristics include a peak non-repetitive surge current of 29,000 A and a maximum junction capacitance of 5200 pF.

Feature Summary

Proprietary barrier technology enables reliable operation up to 150 °C junction temperature with moderate leakage.
Optimized for very low forward voltage drop to enhance efficiency in power conversion applications.
High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance.
Guard ring design ensures enhanced ruggedness and long-term reliability under demanding conditions.

Applications

Switching power supplies
Converters
Free-wheeling diodes
Reverse battery protection

Procurement Notes

Verify the specific voltage rating suffix (e.g., 035, 040, 045) against the required circuit reverse voltage. Confirm that the D-67 Half-Pak mounting dimensions and torque specifications align with the heatsink interface. Ensure thermal management strategies account for the specified thermal resistance values to maintain junction temperatures within the 150 °C limit during continuous operation.

Selection Notes

Select this component when high current handling and low conduction losses are critical. The D-67 package offers a lower profile and easier mounting compared to parallel DO-5 configurations. Consider the 150 °C operating capability for high-temperature environments. Verify that the 29,000 A surge rating meets the system's transient requirements.

Part Context

This part belongs to the 120NQ...(R) series of high current Schottky rectifier modules from Vishay General Semiconductor - Diodes Division. The series is characterized by optimized forward voltage drops and robust packaging suitable for industrial-level applications. The 'R' designation typically indicates a specific terminal or configuration variant within the D-67 Half-Pak family.
