Description:
The C945 is an Bipolar audio frequency NPN transistor. It has a decent gain value (hfe) of maximum 700 and is highly linear. Hence it was widely used in amplifier applications for pre-amplifying purpose, in high frequency circuits. It is also used as oscillators with is complementary A733 PNP transistor
When used as a switch it can easily by controlled by a MCU/MPU since it has a base voltage of only 5V. It can switch loads up to 50V but has a very low collector current rating of 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
