The HMA2701BR3 is a 4-pin mini-flat package optocoupler consisting of two inverse-parallel gallium arsenide infrared emitters driving a single silicon phototransistor, designed for AC line monitoring, unknown polarity DC sensing, and digital logic isolation. It has a lead pitch of 2.54 mm and a maximum standoff height of 2.4 mm. The device supports a continuous forward current of 50 mA, a collector-emitter voltage of 40 V, and a current transfer ratio between 80% and 160% at 5 mA forward current and 5 V collector-emitter voltage. It meets UL, CSA, BSI, and VDE safety certifications with a standard isolation voltage of 3750 VRMS, creepage and clearance of at least 5 mm, and is rated for operation from -40°C to +100°C. It is available in tape and reel packaging with 180° rotated units for automated assembly. The part is reflow solder compatible at 230°C for 30 seconds.
