The CJ3401 with MOSFET P Trench 30V 4.2A 1.3V @ 250uA 65mO @ 4.2A, 10V SOT-23 (SOT-23-3) RoHS is a surface mount MOSFET transistor that is manufactured by Changjiang. It was specifically designed for use in power supply applications and features an ultra-low on-resistance, high current handle rating and small package size. This component's drain-source voltage is 30V, its P-channel is rated at 4.2A, and its drain-source on-state resistance is 65mO. Further, its gate-source operating voltage is limited to 10V and its gate-source cutoff current is 250uA. Finally, the CJ3401 complies with the European Union's Restriction of Hazardous Substances (RoHS) directives.
