AO3414 Datasheet, PDF (1/4 Pages) Alpha & Omega Semiconductors – N-Channel Enhancement Mode Field Effect Transistor

AO3414
N-Channel Enhancement Mode Field
Effect Transistor
General Description
The AO3414 uses advanced trench technology to provide excellent R_DS(ON) , low gate charge and
operation with gate voltages as low as 1.8V. This device is suitable for use as a load switch or in PWM
applications. Standard Product AO3414 is Pb-free (meets ROHS & Sony 259 specifications). AO3414L
is a Green Product ordering option. AO3414 and AO3414L are electrically identical.
