AO4904
Dual N-Channel Enhancement Mode Field Effect Transistor
with Schottky Diode
Features
VDS (V) = 30V
ID = 6.9A (VGS = 10V)
RDS(ON) < 27mΩ (VGS = 10V)
RDS(ON) < 32mΩ (VGS = 4.5V)
RDS(ON) < 50mΩ (VGS = 2.5V)
SCHOTTKY
VDS (V) = 30V, IF = 3A, VF=0.5V@1A
General Description
The AO4904 uses advanced trench technology to provide
excellent RDS(ON) and low gate charge. The two
MOSFETs make a compact and efficient switch and
synchronous rectifier combination for use in DC-DC
converters. A Schottky diode is co-packaged in parallel
with the synchronous MOSFET to boost efficiency further
Standard Product AO4904 is Pb-free (meets ROHS &
Sony 259 specifications). AO4904L is a Green Product
ordering option. AO4904 and AO4904L are electrically
identical.
