Product Overview

Category

The TLP7830(TL,E) belongs to the category of optocouplers, also known as optoisolators or photocouplers.

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, noise, and other disturbances.

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 offer high voltage isolation and noise immunity.
• They can operate in a wide range of temperatures and have a long lifespan.
