160CMQ040

Overview

The 160CMQ040 is a Schottky diode module manufactured by SMC Diode Solutions. It features a dual common cathode configuration housed in an isolated TO-249AA chassis mount package. The device supports a maximum DC reverse voltage of 40 V and provides an average rectified current of 80 A per diode, totaling 160 A for the pair. Key electrical parameters include a forward voltage of 1.17 V at 160 A and a reverse leakage current of 1.5 mA at 40 V. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Dual common cathode Schottky architecture for efficient power conversion
• Isolated heatsink design integrated into the TO-249AA package
• Low forward voltage drop characteristics for reduced conduction losses

Applications

• High-current DC/DC converter modules
• Free-wheeling rectification in synchronous buck converters
• Power factor correction circuits requiring low loss

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer before integration. Confirm that the thermal interface material and mounting torque specifications align with the target chassis design to ensure reliable operation under high current loads. Check for any recent updates to the pinout or mechanical dimensions.

Selection Notes

Select this component when a compact, high-current dual Schottky solution is required. The isolated TO-249AA package simplifies thermal management compared to non-isolated alternatives. Ensure the application voltage does not exceed the 40 V rating and that the thermal design can handle the heat dissipation associated with 160 A total current.

Part Context

This part belongs to the 160CMQ series of Schottky diode arrays from SMC Diode Solutions. These modules are designed for applications demanding high efficiency and robust thermal performance. The series utilizes advanced Schottky technology to minimize switching losses and improve overall system reliability in power electronics.

Replacement Considerations

The Vishay 163CMQ100 is listed as a similar alternative, though it differs in voltage rating (100 V) and current capacity (160 A). Verify compatibility regarding package dimensions and thermal characteristics before substitution.
