Additional Details

The FDD5N50F features a drain-source voltage (VDS) of 500V and a continuous drain current (ID) of up to 4.1A (depending on the specific conditions and package). Its low gate charge minimizes switching losses, contributing to higher efficiency. The fast switching speed enables higher frequency operation, reducing the size and cost of passive components. The device's avalanche ruggedness provides added protection against voltage transients. It is available in a TO-252 package. This MOSFET is designed to operate over a wide temperature range. The FDD5N50F is well-suited for applications that require high voltage and high speed, making it a popular choice for power supply designers. The device's low on-resistance contributes to reduced conduction losses, further enhancing overall efficiency. The integrated gate resistor simplifies the drive circuit design and reduces EMI.
