H11A3 Optoisolator Transistor with Base Output 5000Vrms 1 Channel 6-PDIP

H11A3 Optoisolator Transistor with Base Output 5000Vrms 1 Channel 6-PDIP 

The H11A3 is an optocoupler (optoisolator) that uses a transistor with a base output, providing electrical isolation between its input and output stages. This component features a high isolation voltage rating of 5000Vrms, making it ideal for protecting sensitive electronic circuits from high-voltage spikes or noise. The H11A3 offers a single channel of isolation, meaning it has one input and one output, with the input consisting of an LED that emits light when driven, which is then detected by a phototransistor on the output side. The H11A3 is packaged in a 6-pin PDIP (Plastic Dual In-line Package), suitable for through-hole mounting, making it easy to integrate into various designs. It is commonly used in signal isolation, data transmission, and power control circuits, particularly in industrial and communication applications where high-voltage isolation is required for safety and performance. This optoisolator is effective for preventing ground loops, reducing electromagnetic interference (EMI), and isolating noisy or high-voltage signals from low-voltage control circuits. It ensures that sensitive components such as microcontrollers and low-voltage logic circuits are protected from high-voltage transients and other electrical disturbances.
