ZXMP4A16K P-Channel MOSFET, 40V, 9.9A, TO-252 (DPAK)

The ZXMP4A16K from Diodes Inc. is a next-generation Trench P-channel enhancement-mode MOSFET, engineered using a unique architecture. This innovative design delivers the optimal combination of exceptionally low on-resistance and rapid switching performance, making it a superior choice for applications demanding high efficiency and precise low-voltage control.

Its fast switching speed minimises power losses during state transitions, which is crucial for improving overall system efficiency. The component also features a low threshold voltage and requires minimal gate drive, simplifying circuit design and reducing the complexity of the driving circuitry. This makes it an accessible and effective solution for a wide range of electronic designs.

Key Advantages

• High Efficiency: Low drain-source on-state resistance (RDS(on)) of just 0.06 ohm reduces conduction losses, leading to cooler operation and better energy utilisation.
• Fast Switching: Enables high-frequency operation in power conversion circuits, suitable for modern, compact power supplies.
• Ease of Use: Low gate-source threshold and drive requirements facilitate integration with low-voltage logic and microcontrollers.
• Robust Construction: Housed in a TO-252 (DPAK) surface-mount package, it offers a reliable footprint for automated assembly and provides good thermal performance for power dissipation up to 9.5W.

With a maximum continuous drain current of 9.9A and a drain-source voltage rating of 40V, this MOSFET is built to handle significant power in a compact form factor. Its MSL 1 (Unlimited) moisture sensitivity level ensures excellent shelf life and ease of handling in manufacturing environments.

Typical Applications

• DC-DC converters and switch-mode power supplies (SMPS)
• Power management units in computing and consumer electronics
• Motor drive control circuits for small
