Description
ON
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.

= DIN EN/IEC60747−5−5 Option (Only Appears
on Component Ordered with this Option)
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.
XX = Two Digit Year Code, e.g. ‘15’
YY = Two Digit Work Week Ranging from ‘01’ to ‘53’
P
= Assembly Package Code
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.
