PC815

Transistor, Photovoltaic Output Optoisolators Overview

The PC815 is a single-channel optocoupler manufactured by Sharp Microelectronics, featuring a Darlington transistor output. It provides an isolation voltage of 5000Vrms and operates within a temperature range of -30°C to 100°C. The device supports a maximum DC forward current of 50 mA with a typical forward voltage of 1.2V. Output specifications include a collector-emitter saturation voltage of up to 1V and a maximum output voltage of 35V. The Darlington configuration enables high current transfer ratios ranging from 600% to 7500% at 1mA input. Rise and fall times are typically 60µs and 53µs respectively. The component is available in a 4-SMD鸥翼 (gull-wing) surface mount package.
