概述

Description

The EL817(C)-F is an optocoupler, specifically a phototransistor optocoupler designed for electrical isolation and signal transfer between different circuits. It features a gallium arsenide (GaAs) infrared light-emitting diode (LED) coupled with a phototransistor, enabling it to transmit signals while preventing direct electrical contact between circuits.
Key specifications include a forward current of up to 20 mA for the LED, a collector-emitter voltage rating of 80 V for the phototransistor, and a typical isolation voltage of 5000 VRMS. The EL817(C)-F is suitable for various applications, including data communication, signal isolation, and interfacing microcontrollers with high-voltage systems.
The "C" variant typically indicates a higher speed or enhanced performance, while the "F" suffix denotes that it is a RoHS-compliant, lead-free product. The EL817(C)-F is widely used in consumer electronics, industrial automation, and automotive systems due to its reliability and efficiency in transferring signals safely.
