AOD4185

Overview

The AOD4185 is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to achieve low on-resistance and gate charge. The device features a Drain-Source Voltage (VDS) of -40V and a Continuous Drain Current (ID) of -40A at VGS = -10V. Maximum On-Resistance (RDS(ON)) is less than 15mΩ at VGS = -10V and less than 20mΩ at VGS = -4.5V. It operates within a junction temperature range of -55°C to 175°C.

Feature Summary

Advanced trench technology for excellent RDS(ON) and low gate charge
Suitable for high current applications due to DPAK/IPAK package thermal resistance
100% UIS tested
100% Rg tested

Applications

Procurement Notes

Verify the specific manufacturer source, as multiple vendors including VBsemi and TECH PUBLIC list this part number. Confirm RoHS compliance status relative to data code 8X11 (Sep 1st 2008). Ensure the component matches the TO-252/DPAK or TO-251/IPAK physical footprint required for your design before ordering.

Selection Notes

Select the AOD4185 for circuits requiring a P-Channel MOSFET with a 40V breakdown voltage and high current handling capabilities up to 40A. Consider the thermal characteristics provided in the datasheet for heat dissipation requirements. Verify that the gate drive voltage supports the specified RDS(ON) thresholds of -4.5V or -10V for optimal performance.

Part Context

The AOD4185 belongs to the AOD/AOI series of P-Channel MOSFETs from Alpha & Omega Semiconductor. It is designed for general-purpose switching applications where low on-resistance and fast switching speeds are critical. The device is available in surface-mount packages such as TO-252 (DPAK) and TO-251 (IPAK).

Replacement Considerations

Check datasheets for other P-Channel MOSFETs with similar VDS (-40V) and ID ratings. Ensure pinout compatibility (Gate, Drain, Source) and package dimensions match if substituting directly into an existing PCB layout.
