DESCRIPTION

The IS205-3, -2, -1 series of optically coupled
isolators consist of infrared light emitting diode
and NPN silicon photo transistor in a standard 6
pin dual in line plastic package with the base pin
unconnected.

FEATURES

l Options :-

10mm lead spread - add G after part no.
Surface mount - add SM after part no.
Tape&reel - add SMT&R after part no.

l Low input current 0.5mA I

F

l High Current Transfer Ratio (50% min)

l High Isolation Voltage (5.3kV

RMS

,7.5kV

PK

)

l Basepin unconnected for improved noise

immunity in high EMI environment

APPLICATIONS

l DC motor controllers

l Industrial systems controllers

l Signal transmission between systems of

different potentials and impedances
