The AO4884 is a power MOSFET (metal–oxide–semiconductor field-effect transistor) manufactured by Alpha and Omega Semiconductor. It is a Logic Level N-Channel enhancement mode design that has extremely low on-state resistance, fast switching speed and excellent thermal stability. It is available in a TO-220 package and is used in a variety of applications, such as DC–DC converters, automotive body and convenience features, and other power supplies. It can handle up to 30 Volts and can be used either in a linear or switching mode. The AO4884 has excellent controller compatibility, making it ideal for use in applications with hundreds of power MOSFETs, or for prototyping or improving existing designs.
