Optoisolators, often called Photocouplers, are optoelectronic components that easily isolate electrical circuits without making direct electrical connection, thereby providing a superior level of protection from hazardous conditions. EL3011S(TB)-V is a Triac, SCR Output Optoisolator, and it is widely used in such applications as load switch and motor control, AC voltage control, and industrial automation.

Typical logic family of EL3011S(TB)-V includes CMOS and TTL. This Optoisolator consists of a LED chip, an integrated circuit and four terminals. It has excellent insulation capability, strong common mode noise immunity, low forward voltage, and fast response. The Input-Output isolation voltage ranges from 1500Vrms. The forward current of LED source is 100mA and the breakdown voltage is more than 6KV. The device stands out from others in the same category with its wide working temperature range of -40°C to +105°C, and its drop-in replacement compatibility with existing designs.

The EL3011S(TB)-V is designed for applications of TRIAC, SCR output, and is typically used for switching AC loads. Its insulation distance is up to 1.5KVrms. The output can drive TRIAC or SCR directly without any additional resistors, and it works very reliably in areas of inductive load, like motors and solenoids. Its LED output is activated when the input voltage rises up to 1.7V.

The main working principle of EL3011S(TB)-V is as follows. When the LED is illuminated, light is generated from the LED chip which triggers the integrated circuit. The IC sends a low-power signal to the TRIAC or SCR output depending on the application. The output then switches on or off in response to the incoming input signal.

In summary, EL3011S(TB)-V is a wide-using photoelectric isolation device used for TRIAC, SCR control, and switching AC loads. It offers superior insulation capability, fast response, wide working temperature range, and simple application. As such, it is an ideal component used in various industrial settings and electrical circuits.
