EL817(S)(A)(TU)-V

Optoisolators – Transistor, Photovoltaic Output are designed to address a wide range of applications and have a variety of features for use in electronic systems. The EL817(S)(A)(TU)-V is a transistor, photovoltaic output optoisolator that offers isolation from both the input and output circuitry. This provides the benefit of protecting the system from any electrical surge, transient or noise that may be present in the input signal.

From a design perspective, the EL817(S)(A)(TU)-V has a variety of features. Firstly, it features a low 9 mA input current providing stable and reliable operation. Secondly, it has a wide range of input voltages from 4.5 V to 40V, making it suitable for use in a wide range of applications. Thirdly, the device also features an alterer photodiode to ensure optical performance and reliability.

The EL817(S)(A)(TU)-V also comes with an enhanced transistor output stage, which provides greater protection against input transients, and it also features a red band for output status indication. It also provides up to 3000 VAC of isolation and comes in a plastic SOT-23 package, making it suitable for use in nearly any electronic system.

The primary application of the EL817(S)(A)(TU)-V is to provide isolation of signals from both input and output circuitry. This isolates the signals and prevents any electrical noise, surge, or transients from affecting the system. The device is also suitable for other applications as well such as voltage detection, ac/dc current sensing, power line rejection, ac/dc voltage applications, and electronic load switching.

At a more fundamental level, the EL817(S)(A)(TU)-V is an optoisolator with an internal photo detector and transistor. The photo detector, typically a photodiode or an alterable photo detector, detects the voltage or current level of the input signal. The opto-coupler then converts this signal to an isolated version of the original signal. This output signal is then used by the electronic system.

The EL817(S)(A)(TU)-V also features an enhanced transistor output stage. This output stage is designed to provide better protection against input transients and also provides a red band for output status indication. This feature is beneficial in applications where it’s important to ensure that the output signal is within its planned operational limits.

The EL817(S)(A)(TU)-V is a high-performance optoisolator in that it offers a high level of isolation, wide voltage input range, low input current, and an enhanced transistor output stage. It is suitable for a wide range of applications and can be used to provide voltage and current levels detection, ac/dc current sensing, power line rejection, ac/dc voltage applications, and electronic load switching.
