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.
