C945 Footprint
The C945 transistor is a general-purpose NPN transistor that can be found in a wide range of commercial and educational electronic circuits. It comes in a TO-93 package, and the maximum load this transistor can drive is roughly 150mA (0.15A), which is sufficient to power several devices in a circuit, such as LEDs, relays, ICs, transistors, and other components. The transistor's saturation value is merely 0.3V, which is another positive attribute of this transistor. In addition, the transistor is a low-noise device with an excellent DC gain of 70 to 700.

C945 is commonly used in electrical circuits that require a high-speed transistor with a low current, which is made up of three semiconductor regions: emitter, base, and collector. The base of the C-945 is doped with positive or P-type semiconducting material because it is a bipolar junction transistor.

The C945 transistor has a good DC gain and a low noise type, making it perfect for use in audio preamplifier and amplifier circuit stages, as well as signal amplification in electronic circuits. Most BJT transistors have a saturation voltage of 0.6V, but the C945 has just 0.3V, therefore it can be used in low voltage circuits or in any circuit where the base voltage is low and other BJT transistors are not saturating. It can also be utilized in RF circuits with a frequency of less than 200MHz.
