83CNQ100ASL

Overview

The VS-83CNQ100ASL is a center tap Schottky rectifier module from Vishay, utilizing the D-61-8-SL package. It features two independent legs with a common cathode configuration. The device supports a maximum average forward current of 40 A per leg (80 A total) and a repetitive peak reverse voltage of 100 V. Key electrical parameters include a maximum forward voltage drop of 0.82 V at 80 A and 125 °C, and a non-repetitive surge current capability of 7000 A for 5 μs pulses. The junction temperature range spans from -55 °C to +175 °C.

Feature Summary

• Center tap module design with dual anodes and a common cathode for efficient power conversion
• 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 integrated to improve ruggedness and long-term reliability

Applications

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

Procurement Notes

Verify the specific ordering suffix ASL corresponds to the D-61-8-SL package style before procurement. Confirm that the component meets industrial level qualification requirements. Ensure thermal management solutions account for the specified thermal resistance values. Check for lead-free compliance if required by assembly standards. Validate that the 100 V rating aligns with the system's peak reverse voltage demands.

Selection Notes

Select this component when high frequency operation and low forward voltage drop are critical for efficiency. The 175 °C operating capability allows for reduced heatsinking in high-temperature environments. Compare the 80 A total current rating against load requirements. Consider the D-61-8-SL package dimensions for PCB layout constraints. Evaluate the 7000 A surge current rating for inrush protection needs.

Part Context

This part belongs to the VS-83CNQ...A series of new generation 3 Schottky rectifiers. It shares the same electrical characteristics as the VS-83CNQ080A but offers a higher 100 V reverse voltage rating. The series is optimized for low reverse leakage at high temperatures. It utilizes the proprietary barrier technology developed by Vishay High Power Products.

Replacement Considerations

The VS-83CNQ080A is a direct substitute within the same series, differing only in the 80 V reverse voltage rating. Ensure the application voltage does not exceed 80 V when considering this alternative. Other packages in the series, such as ASM or standard A, share identical electrical specifications but differ in physical mounting styles.
