AO3442 Datasheet, PDF (1/5 Pages) Alpha & Omega Semiconductors – 100V N-Channel MOSFET

AO3442
100V N-Channel MOSFET
General Description
The AO3442 combines advanced trench MOSFET
technology with a low resistance package to provide
extremely low R_DS(ON). This device is ideal for boost
converters and synchronous rectifiers for consumer,
telecom, industrial power supplies and LED backlighting.
