Transistors
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.

MMBT2222ALT3G
Bipolar (BJT) Transistor NPN 40V 600 mA 300MHz 300 mW Surface Mount SOT-23-3 (TO-236) The MMBT2222ALT3G is a NPN general-purpose bipolar junction transistor (BJT) manufactured by onsemi, designed in a SOT-23 surface-mount package. It is the SMD version of the well-known 2N2222A transistor family, used for switching and signal amplification in compact electronic circuits. It is widely used in industrial, automotive (AEC-Q101 qualified variants), and general embedded systems due to its reliability, small size, and good electrical performance. Key Features NPN General-Purpose Transistor Suitable for switching and low-power amplification Collector-Emitter Voltage (Vceo) Up to 40 V Collector Current Up to 600 mA Power Dissipation Around 225–300 mW (depending on package conditions) High Frequency Performance Transition frequency up to ~300 MHz DC Current Gain (hFE) Typically ~100 at moderate currents Low Saturation Voltage Efficient switching performance for digital circuits SOT-23 Surface-Mount Package Compact footprint for modern PCB designs Wide Temperature Range Typically -55°C to +150°C RoHS / Lead-Free Compliant Environmentally compliant manufacturing Typical Applications LED switching circuits Relay driver stages MCU signal interfacing (Arduino, ESP32, etc.) Small motor drivers General signal amplification Automotive and industrial control circuits Important Note MMBT2222ALT3G = SMD version (SOT-23) Equivalent to 2N2222A (TO-92 through-hole version) in function, but not in physical package. 2N2222A SOT-23 #commonpartslibrary #transistor #bjt
