82CNQ030ASL

Overview

The VS-82CNQ030ASL is a dual common cathode Schottky rectifier module rated for 30 V maximum DC reverse voltage and 80 A total average forward current. It utilizes the D-61-8-SL package with leaded termination. The device operates at junction temperatures from -55 °C to 150 °C, featuring a typical forward voltage drop of 0.47 V at 40 A per leg (25 °C). Non-repetitive surge current reaches 5100 A, while thermal resistance from junction to case is 0.85 °C/W per leg.

Feature Summary

• Dual center tap configuration optimized for low forward voltage drop
• High frequency operation capability with high purity epoxy encapsulation
• Guard ring design enhances ruggedness and long-term reliability
• Qualified for industrial level applications up to 150 °C junction temperature

Applications

• Switching power supplies
• Converters
• Freewheeling diodes
• Reverse battery protection

Procurement Notes

Verify the specific ordering suffix ASL corresponds to the D-61-8-SL leaded package variant. Confirm standard pack quantity is 20 pieces as documented for this suffix. Ensure technical requirements align with the 30 V rating and 80 A current capacity before finalizing procurement.

Selection Notes

Select this component for high-current applications requiring low forward voltage drop and fast switching speeds. The dual common cathode topology suits bridge or center-tap circuits. Verify thermal management capabilities against the 0.85 °C/W junction-to-case resistance for the intended operating environment.

Part Context

This part belongs to the Vishay High Power Products Schottky Rectifier series utilizing the New Generation 3 D-61 package family. The '82' designation indicates an 80 A current rating, while '030' specifies the 30 V voltage class. The ASL suffix identifies the specific leaded terminal configuration within this product line.

Replacement Considerations

Direct substitutes include the VS-82CNQ030A (D-61-8) and VS-82CNQ030ASM (D-61-8-SM), which share identical electrical characteristics but differ in package termination style.
