Optoisolators are optoelectronic components used to provide electrical isolation between two or more points in a circuit. They isolate an input from an output and protect sensitive electronics from voltage spikes or other potentially damaging electrical events. The optoisolator family is extensive; within the category, the EL3H7(E)-VG is a transistor, photovoltaic output component.

The EL3H7(E)-VG is a compact, single-piece unit, with an 8-pin dual in-line package design. The package includes a plastic light pipe that relays the incoming signals from the input, through which the two input pins, 1a and 1b, connect and to the LED board inside. Connected to the cathode and anode of the LED respectively, the 1a and 1b pins control the power and functioning of the LED.

Outwardly, the EL3H7(E)-VG package includes two output pins: collector (2) and emitter (3). The output circuit has an open collector, enabling it to sink an unlimited current. When the LED receives an on-state input signal, it emits a light beam. This beam travels within the package and is detected by a photovoltaic detector, completing the electrical circuit within the EL3H7(E)-VG.

The main application and purpose of the EL3H7(E)-VG is isolation against high voltage applications. The device aids with isolating the supply rail from the control input and provides galvanic isolation, stopping hazardous voltage from reaching sensitive circuits. It is particularly useful in medical equipment, instrumentation and other systems where safety is paramount.

The EL3H7(E)-VG is a versatile component, as it can also be used in place of relays in circuits. By utilizing the LED’s low-on-state resistance and its triggered switching time, the EL3H7(E)-VG can be used in any circuit in place of a relay. It also has faster switching times and can operate in temperatures between -55°C and 85°C.

The EL3H7(E)-VG transistor, photovoltaic output optoisolator offers a variety of application potentials while providing a reliable and safe means of electrical isolation. In its small package, it carries the LED output current with a continuous current transfer ratio of up to approximately 5mA, and a maximum LED output voltage of 1.2V. It is an effective and efficient solution for electrical isolation needs and low power switching.
