AO7800
Dual N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO7800 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. Standard Product AO7800 is Pb-
free (meets ROHS & Sony 259 specifications).
AO7800L is a Green Product ordering option.
AO7800 and AO7800L are electrically identical.
