The HMAA2705V is a 4-pin mini-flat package optocoupler consisting of two inverse-parallel gallium arsenide infrared emitting diodes driving a single silicon phototransistor, designed for AC line monitoring, unknown polarity DC sensing, and telephone line reception. It features a lead pitch of 2.54 mm, a maximum standoff height of 2.4 mm, and a typical creepage and clearance of 5.2 mm. The device has a steady-state isolation voltage of 3750 VRMS and a current transfer ratio range of 50-300% at I_F = ±5 mA and V_CE = 5 V. It is certified by BSI, CSA, UL, and VDE, and supports reflow soldering up to 230°C for 30 seconds. The VDE marking indicates compliance with VDE standards as specified in the ordering options.
