HIGH DENSITY MOUNTING
HIGH VOLTAGE DARLINGTON
OPTICALLY COUPLED ISOLATORS
DESCRIPTION
The IS452 is an optically coupled isolator
consisting of an infrared light emitting diode
and a high voltage NPN silicon photo
darlington which has an integral base-emitter
resistor to optimise switching speed and
elevated temperature characteristics in a space
efficient dual in line plastic package.

l Current Transfer Ratio MIN. 1000%
l High collector-emitter voltage, Vceo=300V
l Isolation Voltage (3.75kV
l All electrical parameters 100% tested
l Drop in replacement for Sharp PC452
RMS
,5.3kV
)
PK
APPLICATIONS
