Description

The FOD3120 is a 2.5A Output Current Gate Drive

Optocoupler, capable of driving most 1200V/20A

IGBT/MOSFET. It is ideally suited for fast switching

driving of power IGBT and MOSFETs used in motor

control inverter applications, and high performance

power system.

technology, Optoplanar®, and optimized IC design to

achieve high noise immunity, characterized by high

common mode rejection.

It consists of a gallium aluminum arsenide (AlGaAs) light

emitting diode optically coupled to an integrated circuit

with a high-speed driver for push-pull MOSFET output

stage.

It utilizes Fairchild’s proprietary coplanar packaging
