MURF1640CT

Overview

The MURF1640CT is a high-efficiency recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a dual common cathode configuration housed in an ITO-220AB package with isolated tabs for through-hole mounting. The device supports a maximum repetitive peak reverse voltage of 400 V and provides an average rectified output current of 16 A per diode element. Key electrical characteristics include a fast reverse recovery time of 50 ns, a forward voltage drop of 1.3 V at 8 A, and a low reverse leakage current of 10 µA at 400 V. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• High efficiency ultra-fast recovery design optimized for high-frequency switching applications
• Dual common cathode configuration providing two independent rectifying elements in a single package
• Isolated tab construction allowing direct heat sinking without additional insulators
• Guard ring structure engineered to enhance ruggedness and ensure long-term reliability

Applications

• Switching power supplies requiring fast recovery characteristics
• DC-to-DC converters utilizing high-frequency operation
• Freewheeling diode circuits in inductive load management
• Reverse battery protection systems in automotive or industrial electronics

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as C0G may indicate distinct packaging or compliance attributes. Confirm that the required package type matches the ITO-220AB footprint rather than standard TO-220 variants. Ensure procurement channels provide official datasheets to validate RoHS3 and REACH compliance status prior to integration into regulated assemblies.

Selection Notes

Select this component for designs demanding rapid reverse recovery to minimize switching losses and electromagnetic interference. The 16 A current rating suits moderate to high-power applications where thermal management is feasible via the isolated tab. Consider the 400 V blocking capability for medium-voltage DC bus applications. Evaluate thermal resistance requirements against the expected ambient conditions to ensure junction temperatures remain within the specified 150°C limit during continuous operation.

Part Context

This part belongs to the MURF series of high-efficiency recovery rectifiers from Taiwan Semiconductor. It serves as a specialized variant within the broader MUR family, distinguished by its enhanced speed and efficiency metrics compared to standard fast recovery diodes. The ITO-220AB package offers a robust mechanical solution for through-hole mounting, bridging the gap between smaller surface-mount devices and larger power modules.

Replacement Considerations

The MUR1640CTH is a documented alternative from the same manufacturer featuring similar electrical specifications but potentially differing in automotive qualification status. Verify pinout compatibility and thermal performance characteristics before substituting. Cross-reference with other MURF series parts if current or voltage ratings require adjustment.
