The H11AA1M is a 6-pin DIP AC input phototransistor optocoupler designed for AC line monitoring and unknown polarity DC sensing. It features two gallium-arsenide infrared emitting diodes connected in inverse parallel driving a single silicon phototransistor output, with built-in reverse polarity protection. The device meets UL1577 with 4,170 VAC RMS isolation for 1 minute and complies with DIN-EN/IEC60747-5-5 for 850 V peak working insulation voltage. External creepage and clearance are both ≥7 mm, with ≥0.5 mm distance through insulation. The maximum operating temperature is 100°C, and the collector current is limited to 50 mA. Current transfer ratio ranges from 20% minimum at ±10 mA forward current. The package is a 6-pin DIP with a standard lead spacing.
