Additional Details

The RK7002 typically has a drain-source voltage (V_DSS) rating of 60V, and the continuous drain current (I_D) rating depends on thermal conditions. Gate-source voltage (V_GS) rating is usually ±20V. The on-resistance (R_DS(on)) is a crucial parameter, specified at a specific gate-source voltage and drain current. This MOSFET is offered in a small SOT-23 or similar surface-mount package. It’s crucial to consult the datasheet for specific details and application guidelines including thermal considerations, and the Safe Operating Area (SOA).
