The EL817 Optocoupler series offers a high-performance solution for applications requiring electrical isolation. It features a current transfer ratio (CTR) ranging from 50% to 600% at IF = 5mA and VCE = 5V, ensuring efficient signal transfer between input and output circuits. It provides reliable isolation in demanding environments with a high isolation voltage of 5000Vrms and a creepage distance exceeding 7.62mm.

Operating temperature up to +110°C allows versatility in various industrial and electronic applications. Packaged in a compact small outline package, it offers convenience in assembly and integration. Additionally, the EL817 series is Pb-free, RoHS compliant, and holds multiple certifications including UL, VDE, SEMKO, NEMKO, DEMKO, FIMKO, and CSA approval, ensuring compliance with international safety standards.

The EL817 series consists of infrared emitting diodes optically coupled to phototransistor detectors, housed in a 4-pin DIP package available in both wide-lead spacing and SMD options. Its wide range of applications includes programmable controllers, system appliances, telecommunication equipment, home appliances, and signal transmission between circuits of different potentials and impedances.
