Description

AboutEverlight EL817 PC817 SMD Optocoupler SOP4:

The EL817 or PC817 is a popular optocoupler, also known as an optical coupler or isolator, that provides electrical isolation between two circuits. It achieves this by using an LED (light-emitting diode) to transmit light to a phototransistor on the other side of the device. This isolation barrier prevents high voltages or transients on one side of the circuit from affecting the other side.

Key Features of Optocoupler:

High isolation voltage (5000 V Peak)
High-speed switching (400 kHz)
Industry-standard DIP-4 package
Through-hole mounting for easy assembly
Low power consumption

Benefits of Optocoupler:

Protects sensitive circuits from high voltages or transients
Allows for safe signal transmission between circuits with different ground potentials
Improves noise immunity
Simplifies circuit design

Applications of Optocoupler:
