It can also be used in RF circuits under 200MHz frequency. The saturation voltage of most BJT transistors are 0.6V but the C945 has only 0.3V therefore it can perform well in low voltage circuits or in any circuit where low base voltage is available and other BJT transistors are not saturating. Moreover the transistor is also low noise device, and has a good DC current gain that is 70 to 700.Īs discussed above the transistor has a good DC current gain and low noise type due to which it is ideal to use in audio preamplifier & audio amplifier circuits stages or amplification of other signals in electronic circuits.

The saturation voltage of the transistor is only 0.3V which is also a good feature of this transistor. It is manufactured in TO-93 package, the max load this transistor can drive is around 150mA or 0.15A that is enough to operate many devices in a circuit for example LEDs, Relays, ICs, transistors and other parts of a circuit.

Max Storage & Operating temperature Should Be: -55 to +150 CentigradeĢN2222, 2N3904, 2SC1815, 2SC3198 (Pin configuration of SOME transistors are different from C945, check pin configuration before replacing in a circuit)Ĭ945 is a general purpose NPN transistor used in wide variety of commercial and educational electronic circuits.
