HCPL-814-50AE

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-814-50AE is a single-channel AC input phototransistor optocoupler designed for high-density applications. It features a 5000 Vrms isolation voltage and operates directly from AC input current without external rectification. The device integrates two inverse-parallel LEDs coupled to a phototransistor, providing low collector dark current (max 10^-7 A at VCE = 20 V) and a maximum collector-emitter saturation voltage of 200 mV. It supports an operating temperature range of -30°C to 100°C and utilizes a 4-SMD gull-wing package.
