113CNQ100A

Overview

The Vishay VS-113CNQ100A is a center tap Schottky rectifier module featuring two independent legs with a common cathode configuration. It utilizes the D-61 package and supports a maximum average forward current of 110 A (55 A per leg) and a repetitive peak reverse voltage of 100 V. The device operates within a junction temperature range of -55 °C to +175 °C, offering a typical forward voltage drop of 0.67 V at 55 Apk and 125 °C. It withstands non-repetitive surge currents up to 7000 A and includes guard ring technology for enhanced ruggedness.

Feature Summary

• Center tap dual anode common cathode configuration optimized for low reverse leakage at high temperatures
• Proprietary barrier technology enabling reliable operation up to 175 °C junction temperature
• High purity epoxy encapsulation providing enhanced mechanical strength and moisture resistance
• Guard ring structure designed to improve long-term reliability and ruggedness

Applications

• Switching power supplies
• DC-DC converters
• Freewheeling diodes
• Reverse battery protection circuits

Procurement Notes

Verify the specific package variant required, as the series includes standard leaded (PbF), surface mount (ASM), and low profile (ASL) options. Confirm compliance with RoHS directives by checking the ordering suffix. Ensure thermal management design accounts for the specified thermal resistance values when mounting on heatsinks. Validate that the application current does not exceed the 55 A per leg rating under expected case temperatures.

Selection Notes

Select this component for applications requiring high frequency operation and low forward voltage drop in a compact footprint. The common cathode layout simplifies circuit design for center-tapped transformer configurations. Consider the 175 °C operating capability for environments with limited cooling. Verify that the 100 V reverse voltage rating provides sufficient margin for the specific DC bus or line voltage being rectified.

Part Context

This part belongs to the VS-113CNQ100A PbF Series from Vishay High Power Products. It represents a new generation 3 D-61 package design intended to replace older modules with improved current density and lower profile dimensions. The series is engineered for industrial level qualification and robust performance in demanding power conversion environments.

Replacement Considerations

Direct substitutes include other Vishay center tap Schottky modules with identical 100 V ratings and comparable current capabilities, such as the VS-113CTQ100A. Verify pinout compatibility and thermal resistance specifications before swapping to ensure equivalent heat dissipation performance.
