The AO4805 is a dual P-channel enhancement mode field effect transistor manufactured by Alpha & Omega Semiconductor. It features a 30V drain-source voltage (Vdss) and is housed in an 8-SOIC surface-mount package. The device utilizes advanced trench technology to achieve low on-resistance, making it suitable for power management applications requiring efficient switching of dual P-channel loads.
The AO4805 belongs to the AO48xx series of dual MOSFETs from Alpha & Omega Semiconductor. This series typically offers complementary N-channel and P-channel options in compact packages, designed for portable electronics and battery-powered devices where space efficiency and switching speed are critical.
Direct replacements include other 30V dual P-channel MOSFETs in 8-SOIC packages such as the AO4803 or AO4807 from the same manufacturer. Cross-manufacturer equivalents should match the Vdss, Id, and Rds(on) specifications while ensuring pin compatibility.
