描述 Description

The FOD8342 series is a 3.0 A output current gate drive

optocoupler, capable of driving medium?power IGBT/ MOSFETs. It

is ideally suited for fast?switching driving of power IGBT

and MOSFET used in motor?control inverter applications,

and high?performance power systems.

The FOD8342 series utilizes stretched body package to achieve

8 mm creepage and clearance distances (FOD8342T), and optimized

IC design to achieve reliably high?insulation voltage and high?noise

immunity.

The FOD8342 series consists of an Aluminum Gallium Arsenide

(AlGaAs) Light?Emitting Diode (LED) optically coupled

to an integrated circuit with a high?speed driver for push?pull

MOSFET output stage. The device is housed in a stretched body,

6?pin, small outline, plastic package.
