85CNQ015ASM

Overview

The Vishay VS-85CNQ015ASM is a center tap Schottky rectifier module featuring two anodes and a common cathode base. It provides a maximum average forward current of 80 A and a repetitive peak reverse voltage of 15 V. The device operates with a junction temperature range from -55 °C to +125 °C. Electrical characteristics include a maximum forward voltage drop of 0.45 V at 80 A and 75 °C, and a non-repetitive surge current capability of 5200 A for 5 μs sine pulses. The component utilizes the D-61-8-SM through-hole package.

Procurement Notes

Verify the specific ordering suffix ASM against the datasheet to confirm the D-61-8-SM package style. Ensure the procurement documentation explicitly states lead-free (PbF) compliance if required by the design specifications. Confirm that the requested quantity matches the standard pack size defined in the manufacturer's ordering information table.

Selection Notes

Select this component when designing systems requiring low forward voltage drops for high-efficiency parallel power supply configurations. The 15 V rating suits low-voltage applications where minimal conduction loss is critical. Verify thermal management requirements based on the specified thermal resistance values and allowable case temperatures under expected load conditions.

FAQ

What is the maximum non-repetitive surge current per leg?

The maximum non-repetitive surge current per leg is 5200 A for a 5 μs sine pulse or 3 μs rectangular pulse.

How does the forward voltage drop vary with junction temperature?

The forward voltage drop decreases as the junction temperature increases; it is rated at 0.45 V at 75 °C and lower values at higher temperatures like 100 °C.

What is the typical series inductance per leg?

The typical series inductance per leg is 5.5 nH, measured from lead to lead 5 mm from the package body.
