HCPL2730M

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL2730M is a dual-channel high-speed optocoupler manufactured by onsemi. It integrates an AlGaAs infrared LED with a split Darlington photodetector to provide electrical isolation between input and output circuits. The device features a DIP-8 surface mount package and supports a wide operating temperature range from -40°C to +100°C. Key electrical specifications include a maximum insulation voltage of 5000 Vrms, a typical current transfer ratio of 2400%, and a forward current of 20 mA. The output stage can handle up to 60 mA of collector current with a power dissipation rating of 35 mW.
