AOD4185 Description

Short technical summary and product information.

The AOD4185 is a P-Channel MOSFET from Alpha & Omega Semiconductor, utilizing advanced trench technology to deliver excellent on-resistance and low gate charge. It is rated for a maximum drain-source voltage of -40V and a continuous drain current of -40A at Tc=25°C. The device features a maximum on-resistance of 15mΩ at Vgs=-10V and Id=-20A, and 20mΩ at Vgs=-4.5V and Id=-15A. Total gate charge is 55nC maximum, enabling efficient switching performance. The MOSFET is 100% UIS and Rg tested, ensuring ruggedness in demanding applications. It operates over a junction temperature range of -55°C to 175°C. The AOD4185 is offered in a TO-252-3, DPak (2 Leads + Tab), SC-63 surface mount package, with a supplier device package of TO-252 (DPAK). It is RoHS3 compliant and Halogen Free, making it suitable for environmentally conscious designs. Typical applications include high current load switching, battery protection, power management, and DC-DC converter circuits.
