Fairchild AC Input Phototransistor Optocouplers Data Handbook
Summary
The H11AAX-M series consists of AC input phototransistor optocouplers featuring two gallium-arsenide infrared emitting diodes connected in inverse parallel, driving a single silicon phototransistor output. Key features include bi-polar emitter input, built-in reverse polarity protection, UL recognition, and VDE approval. Available in H11AA1-M through H11AA4-M variants, these devices are designed for AC line monitoring, unknown polarity DC sensing, and telephone line interface applications. Suitable for industrial control systems and telecommunications equipment designers.
