AO7404 Datasheet, PDF (1/4 Pages) Alpha & Omega Semiconductors – N-Channel Enhancement Mode Field Effect Transistor

AO7404
N-Channel Enhancement Mode Field
Effect Transistor
General Description
The AO7404 uses advanced trench technology to provide excellent R_DS(ON) , low gate charge and
operation with gate voltages as low as 1.8V, in the small SOT323 footprint. It can be used for a wide
variety of applications, including load switching, low current inverters and low current DC-DC converters.It
is ESD protected to 1KV HBM. Standard Product AO7404 is Pb-free (meets ROHS & Sony 259
specifications). AO7404L is a Green Product ordering option. AO7404 and AO7404L are electrically identical.
