The SI2302 with MOSFET N Trenche 20V 4A 1.2V @ 250uA 45 mΩ @ 4A,4.5V SOT23 RoHS is a MOSFET (insulated gate field effect transistor), made by PUOLOP. It is a surface mount component in a SOT23 package, meaning it is suitable for automated surface mount assembly. It has a low on-state resistance rating of 45 mΩ when flowing a current of 4A at 4.5V, and its drain to source breakdown voltage (VDSS) is 20V. With a gate source voltage rating of 1.2V at 250uA, the device is highly efficient and can switch quickly at lower gate voltages, making it ideal for a wide range of applications. To meet RoHS (Restriction of Hazardous Substances) requirements, the SI2302 part is free from lead and cadmium, among other hazardous substances.
