The IRLL2705TRPBF is an N-channel enhancement-mode MOSFET from the HEXFET series, rated for a drain-to-source voltage of 55 V and a continuous drain current of 3.8 A at 25°C ambient. It comes in a surface-mount SOT-223 package, which keeps the footprint small but limits power dissipation to 1 W — so the thermal budget is the real constraint for continuous load current above a couple of amps. Rds(on) is 40 mOhm at 3.8 A with 10 V gate drive.
The total gate charge (Qg) at 10 V gate drive is 48 nC. These are moderate values that allow direct logic-level gate drive without a dedicated driver for many switching applications.
