The Alpha & Omega Semiconductor AO3415A is a -20V P-Channel enhancement-mode MOSFET fabricated using advanced trench technology. The 41mOhm maximum RDS(on) at VGS=-4.5V ensures low conduction losses in battery disconnect switches, while the sub-1V threshold voltage (-0.3 to -0.9V) allows direct drive from 1.8V logic outputs without level shifters. The built-in ESD protection diode enhances handling robustness during PCB assembly. In a tiny SOT-23-3 package with 1.5W power dissipation, the AO3415A delivers 5A continuous drain current, making it one of the highest current-density P-Channel MOSFETs available in this package. Note: DigiKey lists this part as Not For New Designs; AOS recommends AOSS21115C as a replacement.

The AO3415A is a P-Channel enhancement-mode MOSFET where current flows from source to drain when a negative gate-source voltage exceeds the threshold voltage (VGS(th) = -0.3 to -0.9V). The trench gate structure provides a vertical channel with very short current path length, achieving low RDS(on) in a small die area. The low 9.3nC total gate charge enables fast switching transitions and lower gate drive power. The ESD protection diode clamps gate-source voltage transients to prevent oxide breakdown. The body diode (inherent in the MOSFET structure) provides a forward path from drain to source when the MOSFET is off.
