85CNQ015ASL

Overview

The VS-85CNQ015ASL is a Schottky rectifier module in the D-61-8-SL package, rated for 15 V maximum DC reverse voltage and 80 A average forward current. It features a common cathode configuration with two anodes. The device operates within a junction temperature range of -55 °C to 125 °C. Key electrical characteristics include a maximum forward voltage drop of 0.45 V at 80 A and 75 °C, and a peak non-repetitive surge current capability of 5200 A.

Feature Summary

• Optimized for ultra-low forward voltage drop specifically for OR-ing parallel power supplies
• Utilizes proprietary barrier technology for reliable operation up to 125 °C junction temperature
• Features guard ring design for enhanced ruggedness and long-term reliability
• Encapsulated in high purity, high temperature epoxy for mechanical strength and moisture resistance

Applications

• Parallel switching power supplies
• Converters
• Reverse battery protection
• Redundant power subsystems

Procurement Notes

Verify the specific ordering suffix 'SL' corresponds to the D-61-8-SL leaded through-hole package variant as defined in the datasheet. Confirm RoHS compliance status and check for any end-of-life notices or alternative recommended parts from Vishay High Power Products before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring low forward voltage drop for efficient power combining. Ensure thermal management accounts for the 0.85 °C/W junction-to-case thermal resistance per leg. Validate that the 15 V rating meets the circuit's reverse voltage requirements and that the 80 A current capacity aligns with load demands.

Part Context

This part belongs to the VS-85CNQ015A PbF Series from Vishay High Power Products. It represents a new generation 3 D-61 package designed for high current applications. The series includes variants such as the standard D-61-8 and surface mount D-61-8-SM packages alongside the SL variant.

Replacement Considerations

Consult the datasheet for recommended alternatives if the ASL suffix is unavailable. Verify pinout compatibility and thermal characteristics when substituting with other D-61 package variants like the ASM or standard A versions.
