Overview
The Vishay 163CNQ100 is a Schottky rectifier module in the 163CNQ series, housed in a TO-249AA package. It features an isolated center tap configuration with two common cathode elements. The device supports a maximum DC reverse voltage of 100 V and delivers a maximum average forward current of 160 A per leg at a case temperature of 122 °C. It operates reliably up to a junction temperature of 175 °C. Key electrical parameters include a peak non-repetitive surge current of 9000 A (5 µs sine) and a typical forward voltage drop of 0.80 V at 80 A.
Feature Summary
- Proprietary barrier technology enables reliable operation at high temperatures up to 175 °C junction temperature.
- Optimized for low reverse leakage current at elevated temperatures.
- High purity, high temperature epoxy encapsulation provides enhanced mechanical strength and moisture resistance.

Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact voltage ratings and package variations. Confirm that the component meets the required industrial level qualification standards. Ensure thermal management solutions align with the specified thermal resistance values for the TO-249AA package.
Selection Notes
Select this component for applications requiring high-frequency operation and low forward voltage drop. Consider the isolated base design when planning heatsinking strategies. Evaluate the thermal resistance characteristics to ensure adequate heat dissipation for the intended duty cycle and ambient conditions.
Part Context
The 163CNQ100 belongs to the 163CNQ series of isolated center tap Schottky rectifier modules. This series is designed for general-purpose applications where high current handling and high-temperature stability are critical requirements.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Verify compatibility regarding pinout configuration, thermal resistance, and voltage ratings before implementation.
