SemiconductorThe ASDM2301ZA/SOT23 is a MOSFET P-channel 20V 3A 1V @ 250uA 85mO @ 3A,4.5V SOT-23 RoHS (Restriction of Hazardous Substances) by Ascend Semiconductor. It is a 3.3mm wide surface mount package with 3 pins, 1 source, 1 drain, and 1 gate. It is equipped with P-channel FET technology allowing high-speed switching, meaning it can quickly turn off and on. This FET has a breakdown voltage of 20V, drain-source on voltage of 1V, drain current of 3A, gate-source threshold voltage of 4.5V, and drain-source on-resistance of 85mO. The maximum gate-source leakage current is 250uA.
