Discrete Semiconductor Kit

If you do anything with electronics, youre probably already using transistors, but youre probably using them in large, prepackaged clusters of just one type. The SparkFun Discrete Semiconductor Kit addresses your needs of only needing one or a couple transistors without you needing go and order a single transistor. Inside each kit you will find multiple types of semiconductors including PNP and NPN bipolar transistors, N-channel and P-channel MOSFETs, diodes, adjustable voltage references, and adjustable voltage regulators.

Because discrete semiconductors are a basic building block of electronic circuits, this assortment of discrete semiconductor makes for a perfect addition to a workbench regardless if you are a beginner or an advanced electronics nerd!
