FDP20N50F Description

Short technical summary and product information.

The FDP20N50F is an N-Channel power MOSFET manufactured by On Semiconductor. It features a drain-source voltage (Vdss) of 500V and a continuous drain current (Id) of 20A at 25°C case temperature. The maximum on-resistance (Rds(on)) is 260mΩ at a gate voltage of 10V and drain current of 10A.

 

This MOSFET uses planar stripe technology and is designed for high-voltage switching applications. Key electrical characteristics include a typical gate charge of 65nC at 10V, input capacitance of 3390pF at 25V drain voltage, and a maximum gate threshold voltage of 5V. The device is capable of dissipating up to 250W at 25°C case temperature.

 

The part is supplied in a through-hole TO-220-3 package, suitable for mounting on printed circuit boards. The operating junction temperature range is -55°C to 150°C, supporting use in harsh environments. The part is designated as RoHS3 compliant and REACH unaffected, though these compliance claims are unverified in the available data.
