Optoisolators - Transistor, Photovoltaic Output

Optoisolators are devices that use light-emitting diodes (LEDs) to transfer signals between two otherwise isolated electrical circuits or systems. They provide electrical insulation between the input and output of the device, making them ideal for use in safety-critical applications. The EL816(S)(TA)-V is an optoisolator designed for photovoltaic output applications. This article will outline the features and working principle of the EL816(S)(TA)-V.

The EL816(S)(TA)-V is an optoisolator designed for photovoltaic output applications. It is a single-stage, bipolar, npn optoisolator with an LED light source. The device is available in a 16-pins surface mount package with optional surge protection. The EL816(S)(TA)-V features low input voltage, high output current, and good common mode transient immunity.

The EL816(S)(TA)-V has a wide range of applications including n-channel half-bridge circuit, single switch isolated high side current sensing, and single switch isolated low side current sensing. In addition, the device can be used for high voltage isolation of digital signals and protection of circuits from high voltage spikes.

The working principle of the EL816(S)(TA)-V is based on the photovoltaic effect. When an LED emits light, electrons in the device will be excited and collected. This energy will then generate a voltage between the anode and cathode of the LED. When the LED is connected to an input signal, the generated voltage will be proportional to the input signal. This voltage will then be transferred to the output circuit, providing electrical isolation between the input and output circuits.

The EL816(S)(TA)-V features an integrated collector-emitter diode for protection against electrical transients. The diode will ensure that the voltage on the output terminal does not exceed a certain predefined threshold. The device also features short-circuit protection, which prevents the output from being overloaded if the load is short-circuited.

The EL816(S)(TA)-V is an ideal optoisolator for photovoltaic output applications. It offers high output current and low input voltage, allowing it to be used for applications ranging from n-channel half-bridge circuits to high voltage isolation of digital signals. The integrated collector-emitter diode and short-circuit protection ensure that the device is safe to use in safety-critical applications.
