# Transistors ## Navigation - [Back to Sitemap](https://www.flux.ai/sitemap.md) - [Back to PCB Footprints](https://www.flux.ai/sitemap/footprints.md) ## Description A transistor is a type of electronic device that controls the flow of electricity or current through a circuit. It acts as a switch or gate, allowing current to pass through or blocking it, depending on the input signal applied to the transistor. Transistors are widely used in a variety of electronic devices and systems, including computers, televisions, radios, and smartphones. They are also used in a range of industrial and medical applications, such as power supply systems and medical equipment. Flux.ai is home to the world's largest community-driven public library of transistors, with footprints, symbols, datasheets, and simulation models available for a wide range of devices. The library is constantly being updated and expanded by a community of engineers and enthusiasts, making it an invaluable resource for anyone working with transistors. Whether you're a student, hobbyist, or professional engineer, you'll find everything you need to know about transistors at Flux.ai. ## Items (Page 1 of 308, 7700 total) - [NSS12201LT1G 12v npn transistor](https://www.flux.ai/georgemars/nss12201lt1g-12v-npn-transistor.md) - SOT-23-3_1P4X3P040_ONS 12v npn transistor - [40V NPN BJT Transistor](https://www.flux.ai/corynrobinson/40v-npn-bjt-transistor.md) - Bipolar (BJT) Transistor NPN 40 V 200 mA 300MHz 625 mW Through Hole TO-92-3.
