Digital Transistors

Digital transistors are discrete semiconductors that are used to amplify electronic signals and electrical power. They take in a tiny electric current at one end of your circuit (an input current) and produce a much bigger electric current at the other end (an output current). In other words, they're a kind of current booster.

How do digital transistors work?

Digital transistors are made of a semiconductor material, usually silicon, which conducts the current (or electricity) with little resistance. They also tend to have at least three terminals for easy connection to an external circuit.

They can also work asswitches.A tiny electric current flowing through one part of a transistor can make a much bigger current flow through another part of it. In other words, the small current can switch on the larger one.

The benefits of using a digital transistor include:

  • a reduction in system cost
  • simplifies your circuit design
  • reduces circuit board space
  • reduces component count

Applications for digital transistors

Digital transistors can be used in several applications including:

  • Control of IC inputs
  • Automotive applications
  • Switching loads
  • Inverter circuits
  • Interface circuits
  • Driver circuits
