Additional Details:

The WNM2021-3/TR possesses a drain-source voltage (VDS) rating. Its continuous drain current (ID) specification depends on the package type and specific operating conditions but generally amounts to several Amperes. The gate threshold voltage (VGS(th)) typically falls around a few volts. The on-resistance (RDS(on)) is typically in the milliohm range which effectively minimizes conduction losses. The device is usually packaged in a surface-mountable format like the SOT-23. It functions effectively over a range of gate drive voltages simplifying integration into circuit designs.
