Additional Details

The 20CUT10 is typically available in a TO-220AC package. The operating temperature range is typically from -65°C to +175°C. The ultrafast recovery time is typically in the range of 25ns to 50ns, depending on the operating conditions. Proper heatsinking is required to dissipate heat generated during operation, especially at high currents. The forward voltage drop is typically around 0.8V to 1.0V at rated current. The reverse leakage current is typically in the microampere range. The high surge current capability makes it suitable for applications with frequent start-up cycles.
