Additional Details

The VF20120SG typically features a maximum repetitive reverse voltage of 120V and a forward current of 20A. The forward voltage drop is generally around 0.7V at the rated current, but this value may vary depending on temperature and other operating conditions. It is available in a TO-220AC package. The operating junction temperature ranges from -65°C to +150°C. Its fast switching speed minimizes reverse recovery losses, making it suitable for high-frequency applications. For detailed specifications, including thermal resistance and leakage current, refer to the manufacturer's datasheet. Proper heatsinking may be required depending on the application to maintain the junction temperature within the specified limits.
