AO7403
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO7403 uses advanced trench technology to provide
excellent R
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 2KV HBM. Standard Product
, low gate charge, and operation with gate

A: The value of R
value in any given application depends on the user's specific board design. The current rating is based on the t ≤ 10s thermal resistance
rating.
