K817P/ K827PH/ K847PH
Optocoupler with Phototransistor Output
Description
The K817P/ K827PH/ K847PH consist of a phototransistor optically coupled to a gallium arsenide
infrared-emitting diode in an 4-lead up to 16-lead
plastic dual inline package.
The elements are mounted on one leadframe using
a coplanar technique, providing a fixed distance
between input and output for highest safety
requirements.
Applications
