Diode, Transistor and Thyristor Components

Your Partner for Hard to Find Diode, Thyristor & Transistor Components

Diode, Thyristor and Transistor components are all discrete semiconductor devices which perform an elementary electronic function. A diode is a two-terminal device, and a thyristor and transistor components are three-terminal devices.  A transistor is a type of semiconductor used in electrical components such as AC/DC transformers, radios, electrostatic discharges (ESD), as light sources, and so on. The primary difference between a thyristor and transistor  is that a thyristor can only function as a digital switch.

Need help finding the right diodes, transistors or thyristors?

VRG Components can source any electronic parts that are hard to find – in short supply (allocations), end of life, obsolete or have long lead times – especially diodes, transistors, and thyristors. We do this by leveraging our extensive network of carefully vetted, reliable suppliers to provide you with the right components to meet your needs.

Our mission is to supply hard to find, high quality electronic components to maximize our customer’s production processes. With the ability to source components from more than 500 leading manufacturers we can secure the diodes, transistors and thyristors required for your project.

 Diode, Transistor & Thyristor Applications

A diode, even as the simplest semiconductor component, has a wide variety of applications in modern electronic systems. Various electronic and electrical circuits use this component. Diodes are used in clippers as well as in rectifiers.

The primary function of a thyristor is to control electric current and power by acting as a switch. A thyristor offers protection to circuits with large voltages and currents (up to 6000 V or 4500 A). Thyristors are used in a wide range of electric circuits, from simple burglar alarms to power transmission lines.

A transistor is composed of semiconductor material and is used to amplify or switch electronic signals and electrical power. Some devices and industries transistor components are used in can range from computers and electronics to communications technology such as smartphones.
