EL814S1(TU)-V

Transistor, Photovoltaic Output Optoisolators Overview

The EL814S1(TU)-V is a single-channel optoisolator featuring an infrared emitting diode optically coupled to a phototransistor detector. It utilizes a surface-mount 4-SMD package and provides high isolation voltage of 5000 Vrms between input and output circuits. The device supports a maximum collector-emitter voltage of 80 V and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a typical forward voltage of 1.2 V, a maximum forward current of 60 mA, and a current transfer ratio ranging from 50% to 150%. Rise and fall times are specified at 7 µs and 11 µs respectively under standard test conditions.
