2SC945 C945 50V 0.15A Bipolar NPN Transistor

Bipolar NPN Transistor is an age-old Japanese Bipolar audio frequency NPN transistor. 2SC945 50V NPN transistor has a decent gain value (hfe) of maximum 700 and is highly linear. Hence this bipolar transistor was widely used in amplifier applications for pre-amplifying purpose, in high-frequency circuits. This NPN junction transistor is also used as oscillators with is complementary A733 PNP transistor.
When used as a switch it can easily be controlled by an MCU/MPU since it has a base voltage of only 5V. C945 transistor NPN can switch loads up to 50V but has a very low collector current rating of the only 150mA so this transistor is not really a good choice to be used as a switch. A better alternative for switching applications will be 2N2222.
