Optoisolators - Triac, SCR Output, EL3041S1(TA)-V application field and working principle

Optoisolators are solid-state devices used to provide electrical isolation between an input signal and an output circuit. The Triac, SCR Output Optoisolator EL3041S1(TA)-V is used when circuits must be switched in various AC systems. This optoisolator is a logic output gate and its applications include switching in various AC systems, motor control speed regulating, home appliances, light and electrical heaters, etc. As with other optoisolators, the EL3041S1(TA)-V provides electrical insulation between the input and the output circuits to provide a safe and reliable operation

Working principle

The EL3041S1(TA)-V is a four-terminal optoisolator in which a gallium arsenide infrared emitting diode (IRED) is optically coupled to a silicon controlled rectifier (SCR) with a built-in photovoltaic trigger circuit. It is an AC input device with four terminals. The input is connected to the gate terminal, the anode is connected to the output terminals, and the cathode is connected to the common terminals. The output SCR fires when the input voltage reaches one or more forward gate current of the optoisolator, depending on the input voltage. The optoisolator must be able to detect a forward gate current through the LED of between 0.3 to 3 mA.

Applications

The EL3041S1(TA)-V has a broad range of uses in various AC systems. It can be used for operating light dimmers, power supplies, motor control and speed regulating, and home appliance electronic circuits.
