Digital Transistors

A digital transistor, also called a bipolar digital transistor, is a type of current booster—a discrete semiconductor with three terminals designed for switching applications in digital circuits. They sink a small current at one end of the circuit (the input current) and generate a much larger current (the output current) at the other. Digital transistors are the essential electronic components designed to function as switches rather than amplification. These specialised transistors come in various types, such as bipolar junction transistors (BJTs), MOSFETs (N-channel & P-channel MOSFETs), junction field-effect transistors (JFETs), and IGBTs (insulated gate bipolar transistors). Enrgtech stocks a supreme collection of digital transistors with different mounting types, ideal for a wide variety of applications.

Benefits of Using Digital Transistors

These exquisite transistors offer multiple advantages, such as:

  • Ease of use
  • Simple circuit design
  • Reduced system cost
  • Reduces component count
  • Reduced circuit board space
  • Highly reliable.

How Do Digital Transistors Work?

A digital transistor with built-in resistors works as a switch and comprises semiconductor (usually silicon) materials that allow power conduction with slight resistance. They also feature three terminals that connect to external circuits conveniently. A small current flowing in the transistor’s part can generate a substantial current flowing in another part, which means it can switch small currents to larger ones.

Typical Applications of Digital Transistors

These transistors are found in a vast array of different switching applications, such as:

  • Control of IC Inputs
  • Consumer Applications
  • Automotive Applications
  • Datacom Applications
  • Interface Circuits
  • Driver Circuits
  • Inverter Circuits
  • Cellular Applications
  • Switching Loads
