Description
The CPC1302 is a dual optocoupler with two
identical, independent channels, each having a
unidirectional input and a high-voltage Darlington
output. Light output from the highly efficient infrared
LED activates its associated, optically coupled silicon
NPN photo-Darlington output transistor. The input
LED and the output transistor are separated by a
3750Vrms isolation barrier.
With a LED current of only 1mA, a current transfer
ratio of 1000% to 8000% is guaranteed at the
collector of the 350V Darlington output transistor.
The CPC1302's low input current capability with
high current transfer ratios, output voltage capability,
and isolation barrier rating make it ideal for many
applications such as telecom, industrial, and power
control.
