A transistor is a small electronic component used to switch or amplify electrical signals. It works as a type of switch or amplifier by regulating the current flowing through the device based on a small input current or voltage. Transistors are widely used in almost all electronic devices, such as computers, amplifiers, and radios.
We offer a selection of high-quality transistors including NPN and PNP transistors, MOSFETs, Darlington pairs, and more for use in hobby projects, Arduino and Raspberry Pi experiments, and professional electronics. Some of our popular transistors include the BC547, BC548, BC640, BC550, and TIP120.
