MURF1660CT

Overview

The MURF1660CT is an ultrafast recovery rectifier manufactured by onsemi, designed for high-efficiency switching applications. It features a dual common cathode configuration housed in a TO-220AB package. The device supports a maximum repetitive peak reverse voltage of 600V and provides a total average forward rectified current of 16A, with 8A per leg. Key electrical characteristics include a typical reverse recovery time of 60ns and a maximum non-repetitive peak forward surge current of 100A. The component operates within a junction temperature range of -65°C to +175°C.

Feature Summary

• Ultrafast 60 nanosecond recovery times for efficient switching performance
• Electrically isolated construction eliminating the need for additional isolation hardware
• High temperature glass passivated junction ensuring reliability under thermal stress

Applications

• Switching power supplies
• Inverters
• Free wheeling diodes

Procurement Notes

Verify the specific suffix against official datasheets, as variations may exist between legacy Motorola documentation and current onsemi specifications. Confirm package dimensions and marking codes match the required PCB footprint. Ensure compliance with RoHS directives if applicable to the target assembly process. Cross-reference manufacturer lot codes for authenticity.

Selection Notes

Select this component for circuits requiring fast recovery characteristics at 600V blocking levels. The 16A total current rating suits moderate to high-power conversion stages. Consider thermal management requirements given the 175°C junction limit. Evaluate the TO-220AB package for adequate heat dissipation in the final enclosure design without forced cooling.

Part Context

This device belongs to the MUR series of ultrafast rectifiers, historically associated with Motorola and now produced by onsemi. The series is characterized by epitaxial planar construction and glass passivation. It serves as a standard solution for replacing slower recovery diodes in high-frequency power electronics where efficiency and reduced switching losses are critical design parameters.
