The CJ2302S MOSFET N Trench 20V 2.1A 1.2V @ 50uA 60 mΩ @ 3.6A,4.5V SOT-23 (SOT-23-3) RoHS manufactured by Changjiang is a solid state semiconductor that uses n-type MOSFETs to act as switches, allowing current to flow between two different points. The device is composed of an insulated gate, , three source, drain, and substrate, thus forming an N-channel MOSFET. The device features a breakdown voltage of 20V, an on-state resistance of 60 mΩ at a current of 3.6A, an insulated gate threshold voltage of 1.2V at a gate-to-source current of 50uA, and is RoHS-compliant. It comes in a SOT-23-3 package.
