Working Principles

The EL8171ISZ-T13 optocoupler consists of an infrared LED and a phototransistor. When a current is applied to the LED, it emits infrared light. This light is then detected by the phototransistor, causing it to conduct current between the collector and emitter terminals. The optocoupler provides electrical isolation between the input and output circuits, allowing for signal transmission without direct electrical connection.

Detailed Application Field Plans

The EL8171ISZ-T13 optocoupler is commonly used in the following applications:

1. Power supply circuits: Isolating control signals from high-voltage power sources
2. Industrial automation: Transmitting signals between control systems and sensors/actuators
3. Audio equipment: Isolating audio signals to prevent noise interference
4. Medical devices: Ensuring patient safety by isolating sensitive circuits from external influences
