The FCP21N60N is a single N-channel power MOSFET from onsemi, housed in a TO-220-3 through-hole package. It features a 600 V drain-source breakdown voltage and a continuous drain current of 21 A. The device exhibits a maximum on-resistance of 195 mΩ at 10 V gate drive. Key electrical characteristics include a gate charge of 74 nC, a threshold voltage range of 2 V to 4 V, and a power dissipation capacity of 180 W. Operating temperatures span from -55 °C to +150 °C junction temperature.
Verify the specific datasheet revision and ordering suffixes when sourcing, as manufacturing updates may occur. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to finalizing procurement decisions. Ensure that the component meets all relevant regulatory standards required for your specific application region.
Select this component based on its 600 V rating and 21 A current handling capabilities relative to system requirements. Evaluate the 195 mΩ on-resistance against thermal management constraints to ensure adequate heat sinking. Consider the TO-220-3 package for through-hole mounting compatibility and verify that the gate charge specifications align with the driving circuit's output capabilities.
This part belongs to onsemi’s SupreMOS family of high-voltage N-channel MOSFETs. These devices are engineered for general-purpose power switching applications requiring high reliability and efficiency. The FCP21N60N utilizes advanced silicon planar technology to deliver superior performance compared to standard discrete solutions within the same voltage class.
Direct substitutes include the FCP25N60N and FCP16N60N from the same manufacturer series. Verify pinout compatibility and ensure that the alternative device’s current and voltage ratings meet or exceed the original design specifications before implementation.
