The ZXMP3A17E6 30V, p-channel MOSFET from Zetex employs a unique recessed gate architecture and features low on-resistance with fast switching to ensure high efficiency operation and higher current handling.

At a gate drive of -10V, the SOT23-6 device offers a maximum on-resistance of 70 milliohms for a continuous drain current of 4A and a pulsed drain current of 14.4A. The MOSFET has a total gate charge of 15.8nC for the same gate drive, making the device suitable for high frequency applications.

As a low-loss, high-speed switching solution, the p-channel MOSFET targets dc/dc converter, motor control, and disconnect applications as well as a broad range of power management functions.
