The H11AA4VM is a 6-pin DIP AC input phototransistor optocoupler featuring two gallium-arsenide infrared emitting diodes connected in inverse parallel driving a single silicon phototransistor output. It includes built-in reverse polarity protection and meets UL1577 with 4,170 VAC RMS for 1 minute isolation and DIN-EN/IEC60747-5-5 with 850 V peak working insulation voltage. External creepage and clearance are both ≥7 mm, with an insulation thickness of ≥0.5 mm. The device supports an operating temperature range of -40 to +100°C, has a maximum collector current of 50 mA, and a current transfer ratio of 100% at ±10 mA forward current. It is designed for AC line monitoring, unknown polarity DC sensing, and telephone line interfaces.
