Optoisolators, also referred to as Optical Couplers, are electrical isolation devices used to safely transfer signals between two circuits and prevent any potential damage to any one of them due to transients. They are commonly used to isolate control systems, data buses, and signals that may be subject to high levels of noise, as well as to ensure the integrity of the signal being transferred. Optoisolators are available in a variety of forms such as optical switches, triacs, thyristors, transistors, etc., and are available with outputs for a wide range of both logic and analog applications. The EL357N(TB)-VG is one such optoisolator, which utilizes a transistor-photovoltaic output to achieve isolation between two circuits.

The EL357N(TB)-VG is an optoisolator which features integrated alignment-free optics and a look-through type of push-on LED. It is designed to absorb LED power across a wide range of temperatures and to allow for a high level of immunity to surge and ESD. The maximum collector current rating of the optoisolator is 100mA, with a maximum collector-emitter voltage of 30V. The maximum response time for the optoisolator is 10µs, and the maximum propagation delay time is 4µs. It also features an insulation resistance of 10^9∕s12Vdc and a dielectric strength of 2kV, per UL1577.

The EL357N(TB)-VG optoisolator works based on the principle of optoelectronic signal transmission. In this case, the optoisolator works by using an LED and a phototransistor to enable electrical connections between two isolated circuits. To activate transmission between the two circuits, current is first applied to the LED, which then emits light. This light is then detected by the phototransistor, which then conducts and allows current to flow between the two circuits. The advantages of this type of optoisolator is that it can provide high-voltage isolation and provide a greater level of ESD and surge protection, as well as eliminate ground loops and the need for a common ground signal.

The applications for the EL357N(TB)-VG optoisolator are vast.
