HCPL-7860-500E

Product Overview

Category

HCPL-7860-500E belongs to the category of optocouplers or optoisolators.

Use

Optocouplers are electronic devices that provide electrical isolation between input and output circuits. They are commonly used to transfer signals between two circuits while keeping them electrically isolated, protecting sensitive components from voltage spikes or noise.

Characteristics

• Optocouplers consist of an LED (light-emitting diode) and a phototransistor or photodiode.
• They can transmit signals across an isolation barrier without any direct electrical connection.
• Optocouplers provide high voltage isolation and noise immunity.
• They are compact in size and have low power consumption.
• Optocouplers offer fast response times and high-speed data transmission capabilities.

Working Principles

HCPL-7860-500E works based on the principle of optical coupling. When an electrical signal is applied to the LED (Anode and Cathode), it emits light. This light is then detected by the phototransistor (Collector and Emitter), which converts it back into an electrical signal. The input and output circuits are electrically isolated, allowing for safe signal transmission.
