EL817(S)(TA)-V Typical application Circuitry

EL817(S)(TA)-V

The EL817(S)(TA)-V optocoupler, sometimes referred to as an optical isolator, is made to use light to transmit electrical signals between two isolated circuits. It is made up of a phototransistor and an infrared LED. This component is widely utilized in various applications to provide electrical isolation, thereby protecting sensitive electronics from voltage spikes, eliminating ground loops, and enhancing safety.

Application Scenarios

EL817(S)(TA)-V is suitable for a broad range of applications, including but not limited to, signal isolation in communication systems, interfacing microcontrollers with high-voltage circuits, power supply regulation, and in digital logic circuits where electrical isolation is necessary. A specific application could be in a microcontroller-based system for controlling an AC load via a triac.

Parameter Features

The EL817(S)(TA)-V features high electrical isolation (typically several thousand volts), a Current Transfer Ratio (CTR) that highlights the efficiency of the optical coupling, and a wide operating temperature range. It's designed for low power consumption and high reliability, with a compact package suitable for space-constrained applications.

Circuit Connection Example: Microcontroller-Based AC Load Control

In a microcontroller-based system for controlling an AC load, EL817(S)(TA)-V can be used to isolate the control signals from the microcontroller to the triac driving the AC load.

- Microcontroller to LED Connection: Connect the anode of the internal LED to a digital output pin of the microcontroller through a current-limiting resistor, and connect the cathode to the ground of the microcontroller circuit.Thus, the microcontroller can control the LED and phototransistor.

- Connection of Phototransistor to Triac Gate: The phototransistor's emitter is linked to the ground of the power side circuit, while its collector is connected via a resistor to the triac's gate. The phototransistor conducts based on the LED's light, triggering the triac and allowing current to flow through the AC load.

- Current-Limiting Resistor: Connect a resistor in series with the LED and set the datasheet's recommended safe values for the current flow through the resistor to safeguard it from damage.

- Gate Resistor: A resistor connected between the phototransistor's collector and the triac gate limits the gate current to safe levels, as specified for the triac.

- AC Load Connection: Connect the AC load in series with one of the main terminals of the triac, and connect the other main terminal to the AC supply line.

When designing circuits with EL817(S)(TA)-V, it's crucial to consider the current and voltage requirements of the LED and phototransistor to ensure they operate within their specified limits.The current-limiting resistor's value should be determined using the LED's forward voltage and current as well as the microcontroller's output voltage. The isolation voltage rating of the optocoupler must exceed the maximum voltage that might appear across the isolation barrier to ensure safety and reliability. Additionally, proper PCB layout practices should be followed to maintain the integrity of the electrical isolation and minimize noise coupling.
