K815P

Transistor, Photovoltaic Output Optoisolators Overview

The K815P is a photodarlington optocoupler manufactured by Vishay Semiconductor Opto Division. It consists of an infrared emitting diode optically coupled to a high-gain photodarlington transistor output. The device provides electrical isolation between input and output circuits, rated at 5300Vrms for one channel. It utilizes a gallium arsenide emitter and is designed for applications requiring high current transfer ratio and robust signal transmission across isolated boundaries.
