82CNQ030ASM

Overview

The Vishay VS-82CNQ030ASM is a dual common cathode Schottky rectifier module rated for 30 V maximum reverse voltage and 80 A total average forward current. It utilizes the D-61-8-SM base-mount package with a low-profile footprint. The device operates at junction temperatures up to 150 °C, featuring a typical forward voltage drop of 0.37 V per leg at 40 A and 125 °C. Key electrical characteristics include a peak surge current capability of 5100 A and a maximum thermal resistance of 0.85 °C/W per leg.

Feature Summary

• Dual center tap configuration optimized for very low forward voltage drop
• Proprietary barrier technology enabling reliable operation up to 150 °C junction temperature
• High purity epoxy encapsulation providing enhanced mechanical strength and moisture resistance
• Guard ring design incorporated for improved ruggedness and long-term reliability

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the exact package style. The 'ASM' suffix corresponds to the D-61-8-SM case style, which differs from standard or lead-free variants. Ensure that the required quantity aligns with the standard pack size associated with this specific marking code before finalizing procurement orders.

Selection Notes

Select this component when high-frequency operation and minimal conduction losses are critical requirements. The D-61-8-SM package offers a small footprint suitable for space-constrained designs requiring high current handling. Evaluate the thermal management strategy carefully, as the device supports high average currents but requires appropriate heatsinking to maintain junction temperatures within the specified operating range.

Part Context

This part belongs to the VS-82CNQ030A series, representing Vishay's New Generation 3 D-61 package line. The series includes variations such as the standard D-61-8 and the lead-frameless D-61-8-SL. The ASM variant specifically denotes the surface-mount compatible D-61-8-SM package, designed for industrial-level applications requiring robust performance in demanding environments.

Replacement Considerations

Direct substitutes include the VS-82CNQ030A (D-61-8) and VS-82CNQ030ASL (D-61-8-SL). Verify pinout compatibility and mounting torque specifications when replacing the ASM variant with other package styles in the same series.
