The BC817-25 with SOT-23 Bipolar Transistors - BJT ROHS manufactured by TWGMC is a type of complementary low-noise transistor designed for general amplifier, low noise, and switching applications. It has three terminals- the emitter, collector, and the base- and is designed to be easily interfaced with other circuits and components. The SOT-23 package allows for a low profile quantum well device that can be easily implementation. This device offers a large current gain (beta) over a wide current range and voltage range, allowing for efficient and highly stable operation. Furthermore, its RoHS compliant construction helps protect the environment and users from any toxic materials.
