MUR1660CT Diode Array 1 Pair Common Cathode 600V 8A TO-220

MUR1660CT Diode Array 1 Pair Common Cathode 600V 8A Through Hole TO-220

The MUR1660CT is a high-speed, dual ultrafast recovery diode designed for high-frequency power applications requiring rapid switching and efficient energy management. Packaged in a TO-220-3 through-hole case, this diode array consists of two 8A diodes with a common cathode configuration, making it ideal for use in push-pull and center-tap transformer circuits where symmetrical current handling is essential.

Rated for 600 volts of repetitive reverse voltage and a continuous forward current of 8 amps per diode (16A total), the MUR1660CT delivers excellent performance in harsh environments and demanding power electronics systems. One of its key advantages is its ultrafast reverse recovery time, typically around 50 nanoseconds, which significantly reduces switching losses in high-frequency circuits such as switch-mode power supplies (SMPS), DC-DC converters, and motor drive inverters. This also helps improve overall system efficiency and reduce electromagnetic interference (EMI).

The device features a low forward voltage drop (typically around 1.2V at 8A), minimizing power dissipation and allowing it to operate with lower thermal output. Combined with the TO-220 package’s strong thermal characteristics and capability for heatsink mounting, it ensures reliable operation even at elevated temperatures up to 150°C junction temperature.

The MUR1660CT is commonly used in applications including freewheeling diodes, output rectifiers, snubber circuits, flyback converters, and other high-speed rectification needs in both consumer electronics and industrial environments.

Manufacturers like Taiwan Semiconductor, ON Semiconductor, and Yangjie Electronics offer versions of this component with similar electrical characteristics. Its popularity stems from its balance of speed, power capacity, and robustness, making it a dependable choice for designers working on high-performance, energy-efficient systems. Whether for prototyping or production, the MUR1660CT remains a staple in power diode solutions.
