110CNQ045ASM

Overview

The Vishay VS-110CNQ045ASM is a center tap Schottky rectifier module featuring two anodes and a common cathode configuration. It utilizes the D-61-8-SM package style and operates with a maximum DC reverse voltage of 45 V. The device supports a maximum average forward current of 110 A (55 A per leg) and withstands a non-repetitive surge current of 5400 A. Junction temperature ranges from -55 °C to 150 °C, with a typical forward voltage drop of 0.5 V at 55 Apk.

Feature Summary

• Center tap module design 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 structure designed for improved ruggedness and long-term reliability

Applications

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

Procurement Notes

Verify the specific ordering suffix ASM corresponds to the D-61-8-SM package variant when sourcing replacements. Confirm RoHS compliance status as standard PbF terminations may not meet all regulatory requirements. Validate thermal management specifications against actual application duty cycles to ensure junction temperatures remain within the 150 °C limit during continuous operation.

Selection Notes

Select this component for high-frequency applications requiring moderate leakage characteristics and robust thermal performance. Ensure the mounting surface meets the specified flatness requirements to maintain optimal thermal resistance values. Evaluate the allowable case temperature curves relative to the expected average forward current and duty cycle to prevent overheating in dense circuit layouts.

Part Context

This part belongs to the VS-110CNQ045A PbF Series, representing Vishay's New Generation 3 D-61 package line. The series is engineered for industrial level qualification and features a fully transfer-molded low profile footprint. It serves as a high-current solution within the broader Vishay High Power Products portfolio.

Replacement Considerations

Direct substitutes include the VS-110CNQ045ASLPbF (D-61-8-SL package) and VS-110CNQ045APbF (D-61-8 package). Verify pinout compatibility and physical dimensions before integration, as package styles differ across the series variants.

FAQ

What is the maximum non-repetitive surge current rating?

The device can withstand a peak one-cycle non-repetitive surge current of 5400 A under rated load conditions.

How does the junction temperature affect forward voltage drop?

The forward voltage drop decreases as the junction temperature increases; it is typically 0.54 V at 25 °C and drops to 0.5 V at 125 °C for a 55 A leg current.

What is the typical series inductance per leg?

The typical series inductance is 5.5 nH, measured lead-to-lead at a distance of 5 mm from the package body.
