A “Triode for AC” is a component that is commonly abbreviated into TRIAC, where ‘TRI’ denotes a device with three terminals, and AC implies that it controls alternating current or conducts it in both directions. TRIACs are semiconductor devices used for switching control and power applications, and they are used extensively in fan speed controls, lamp light controls, phase controls, and even modern computerized control units of several household devices. Since TRIACs find widespread application in several industries, learning more about their construction and function becomes imperative.

If you have designed sound systems or have procured various electrical components for them, you may be familiar with the Darlington transistor. Within the realm of electronics, a Darlington pair is used to describe a circuit that contains two bipolar transistors where one emitter is connected to the base of the other. With such a design, all current amplified by the first transistor will be amplified to a greater extent as it passes through the second transistor. Coming in the form of a single package that surpasses the current gain of such transistors when separated, Darlington transistors are common for audio amplifier applications and other electronic components. In this blog, we will discuss the 2N5306 NPN Darlington transistor in particular, that of which is a component found in motor control units, power regulators, and audio amplifiers alike.

Within an electronic assembly or system, various electronic parts and components will work together to establish a complete circuit. All the components within a circuit can be divided into two groups, those of which are active and passive. While active components are those capable of providing energy to a circuit, passive components only receive energy. As both types of components serve different roles in the realm of circuit functionality, it is important to understand the differences between each and their common types.

Within the realm of electronics, relays are switches that are electrically operated, capable of making and breaking contacts to manage circuits. Generally, relays are used in instances where a single circuit is to be managed by a low-power signal, or where multiple circuits are governed through a single signal. Differing in their design and capabilities, there are various switch types that may be used to benefit certain applications. Power relays are a common subtype of relay, featuring an electromagnet that allows them to open and close circuits. Capable of achieving high levels of isolation between the control signal and output, power relays find use in various applications and industries.
