AO4824 Datasheet, PDF (1/7 Pages) Alpha & Omega Semiconductors – Asymmetric Dual N-Channel Enhancement Mode Field Effect Transistor

AO4824
Asymmetric Dual N-Channel Enhancement
Mode Field Effect Transistor
General Description
The AO4824 uses advanced trench technology to provide excellent R DS(ON) and low gate charge. The
two MOSFETs make a compact and efficient switch and synchronous rectifier combination for use in DC-
DC converters._{Standard Product AO4824 is Pb-free} (meets ROHS & Sony 259 specifications). AO4824L
is a Green Product ordering option. AO4824 and AO4824L are electrically identical.
