HMA2701AR2

Transistor, Photovoltaic Output Optoisolators Overview

The onsemi HMA2701AR2 is a single-channel transistor output optocoupler housed in a compact 4-SMD Mini-Flat package with a 2.54 mm lead pitch. It integrates a gallium arsenide infrared emitting diode and a silicon phototransistor to provide electrical isolation. Key electrical parameters include an insulation voltage of 3750 Vrms, a maximum collector-emitter voltage of 40 V, and a maximum collector current of 80 mA. The device supports a forward current of 50 mA with a typical forward voltage of 1.4 V. It operates within a temperature range of -40°C to +100°C and features a current transfer ratio up to 300%.
