EL816(S)(A)(TA)

The EL816(S)(A)(TA) optocoupler is a high performance transistor output optoisolator that provides electrical isolation between input and output circuits. The device features a single silicon phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 6-pin dual-in-line package. The EL816(S)(A)(TA) is capable of high isolation voltage of 5kV and high operating speed of up to 3MHz. It is designed for applications such as pulse width modulation control, logic isolator, over/under voltage protection, DC switching power supplies, and input port isolation in industrial control systems.

The working principle of EL816(S)(A)(TA) optocoupler is based on the principle of light isolation between two circuits. In the circuit, when the input voltage is applied to the anode and cathode of the diode, the diode will be set in forward bias condition and the current will start to flow through the diode. This current will then generate light which will be sensed by the phototransistor. The phototransistor will then amplify the signal and activate its output. As a result, the output of the optocoupler will replicate the input signal in electrical form.

The EL816(S)(A)(TA) optocoupler is typically used in applications where there is an optical barrier between the input and output of a circuit. The device is widely used in communication protocols such as RS-485, Profibus, Modbus, and other serial interfaces. It is also used for providing signal isolation in microcontroller based power inverter circuits. In addition, it can also be used to isolate digital or analog signals and protect against overvoltage and overload.

EL816(S)(A)(TA) optocoupler provides high isolation voltage, high operating speed and low power consumption. It is an ideal solution for isolating and protecting sensitive circuitry in applications where a signal has to be transferred from one circuit to another without establishing any electrical contact. The device is available in a 6-pin dual-in-line package and is designed for reliable operation in extreme environmental conditions such as high temperature and humidity.

In conclusion, the EL816(S)(A)(TA) optocoupler is a widely used optoisolator featuring a single silicon phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 6-pin dual-in-line package. The device provides a robust electrical isolation between input and output circuits, high operating speed, and low power consumption. It is used for a variety of applications such as pulse width modulation control, logic isolator, over/under voltage protection, DC switching power supplies, and input port isolation in industrial control systems.
