The GBPC3502W is a type of P-Channel Power MOSFET (metal-oxide-semiconductor field effect transistor) made by DC Components. This type of MOSFET is used for controlling electrical power to devices through the use of an external voltage. This device features a maximum drain-source voltage of 350V, a maximum continuous drain current of -10A, an on-state resistance of 9.1 mOhm, and a threshold voltage of -2.5V. In addition, it has an integrated freewheeling diode for protection against inductive loads. This device is commonly used in applications such as motor control, liquid level controls, high-power switches, solar cell panel controllers, and more.
