Description
C945 is an age old Japanese Bipolar audio frequency NPN transistor. It has a decent gain value (hfe) of maximum 700 and is highly linear. Hence was widely used in amplifier applications for pre-amplifying purpose, in high frequency circuits. Also used as oscillators with its complementary A733 PNP transistor.
As a switch its easily controlled by a MCU/MPU since it has a base voltage of only 5V. It switches loads upto 50V but has a very low collector current rating of only 150 mA. Therefore, not recommended to be used as a switch.
