Discrete Semiconductors

We have a wide selection of discrete semiconductors across a range of transistors, diodes, rectifiers and modules. There are a number of brands to choose from including ON Semiconductors, Vishay, Infineon and DiodesZetex, amongst others.

What is a discrete semiconductor?

A discrete semiconductor is basically the opposite of an integrated circuit. It is an individual circuit that serves only one function as a single semiconductor, as opposed to multiple semiconductor components that you might find on a printed circuit board (PCB).

They are generally created for high power or frequency functions and as a result require specialist packaging.

What are some examples of discrete semiconductor devices?

Here are some individual device examples:

Thyristors: this type of semiconductor is often used as a switch running specific amounts of current through them
Zener diodes: these discrete devices are the most common type of component for voltage regulation
Bipolar transistors: carry both positive and negative charges in analog circuits
Bridge rectifiers: named so as they are built in specific configuration from diodes
MOSFET transistors: metal oxide semiconductor field effect transistors are widely used for switching and amplifying signals
TRIACs: are bidirectional switches allowing current in both directions
JFET transistors: junction field effect transistors are voltage controlled and as a result provide resistance
Rectifier & Schottky diodes: capable of very fast switching with low voltage drops
DIACs: often used for triggering thyristors
Varactor diodes: found in everyday common appliances and are controlled by the voltage applied through them
