If you do anything with electronics, you’re probably already using transistors, but you’re 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.

Two transistors which will replace a multitude of common hard to get devices. TO-92 package.

Transistors are powerful little electronic switches, and when Adafruit's little NPN transistors aren't power enough for your project, Adafruit have been known to use these beefy...

Make your own smart LEDs with the same chip that is used in Adafruit's NeoPixel strip and pixels. This tiny SOIC-8 is fairly easy to solder and can drive a single common-anode...

This dedicated LC meter offers wider inductance and capacitance ranges than other ‘do-it-all’ meters available on the market. A workbench essential for developing audio crossover circuits, switchmode power supplies and RF circuits. This meter includes a large 30mm, 3.5 digit display and is capable of reading capacitance from 2nF to 1000µF on polarised (electrolytic) and non-polarised capacitors, and inductance from 2mH to 20H. Supplied with high quality silicon rubber croc clip and test probe leads, rubber holster. Features High accuracy inductance & capacitance ranges Jumbo 1999 count readout Battery included Supplied with quality silicon rubber test leads, rubber holster.

The Paris Flyer CarouSol Kit is the latest product in our line of solar-powered kinetic desk toys. Borrowing design elements from the golden age of air travel, we've added our unique solar-electronics flair to create self-powered dynamic mobiles.

The colour-changing LED in this nightlight kit is automatically illuminated and starts to cycle through various patterns when the light sensor has detected that is dark

This is a small ambient light sensor that acts as an NPN transistor. The more the sensor is exposed to light, the stronger the base bias. Simple to use! Simple breakout board available below.
