Diode or transistor – choosing between these two optoelectronic elements may seem difficult, especially for those who are unfamiliar with this sector of technology. Both have their own properties and applications, which determine their choice for specific applications. In this article we take a closer look at these two components and consider the factors that should influence their choice.
Optoelectronic diode
An optoelectronic diode is a semiconductor element that emits light when exposed to an electric current. Among the most common types of optoelectronic diodes are LEDs (light-emitting diodes), which are used in a wide range of applications, from simple signaling diodes to room lighting diodes to advanced signal transmission diodes. Li-Fi data.
An optoelectronic diode is a unidirectional component: it passes current in only one direction, from the anode to the cathode. This property is often used in electronic circuits to protect other components from uncontrolled current flow.
Optoelectronic transistor
An optoelectronic transistor, also known as a phototransistor, is a component that changes its conductive properties when exposed to incident light. Optoelectronic transistors are mainly used as light sensors, both in simple applications such as twilight switches and in advanced measurement systems.
Unlike a diode, an optoelectronic transistor does not emit light, it senses it. As a result, it can be used to build different types of sensors, detectors or optical communication systems.
Choice of element
The choice between a diode and an optoelectronic transistor depends mainly on the function that the element must perform in the system. If we need an element that emits light, the choice should fall on a diode. If, however, it is an element that detects light, the choice falls on a transistor.
