Description

The FOD8343 series is a 4.0 A maximum peak 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 FOD8343 series utilizes stretched body package to achieve

8 mm creepage and clearance distances (FOD8343T), and optimized

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

immunity.

The FOD8343 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.
