AO4618

Overview

The AO4618 is a complementary N- and P-channel MOSFET manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver low on-resistance and gate charge. The device features a drain-source voltage of 40V for both channels. Continuous drain current ratings are specified at 8A for the N-channel and -7A for the P-channel, measured at VGS=10V. Maximum on-resistance values are less than 19mΩ for the N-channel and 23mΩ for the P-channel at VGS=10V. At VGS=4.5V, maximum on-resistance remains below 27mΩ for the N-channel and 30mΩ for the P-channel.

Feature Summary

Advanced trench technology implementation for optimized performance
Low gate charge characteristics for efficient switching
Complementary configuration suitable for low input voltage inverter applications

Applications

Low input voltage inverter circuits
Power management systems requiring complementary switching
DC-DC converter topologies

Part Context

The AO4618 belongs to the AO46xx series of complementary MOSFETs from Alpha & Omega Semiconductor. This series is characterized by the use of trench technology to achieve low RDS(ON) and fast switching speeds within an 8-pin SOIC package. The component is designed for applications demanding high efficiency in low-voltage environments.

Replacement Considerations

Public confirmed substitute part numbers include DMC4028SSD, DMC4040SSD, and ZXMC4A16DN8. These alternatives offer similar 40V complementary configurations. Verify pinout compatibility and specific electrical parameters against the AO4618 datasheet before substitution.
