About this item
Product details
The C945 is an old Japanese bipolar audio frequency NPN transistor. It has a decent gain value (hfe) of a maximum of 700 and is highly linear. It has been widely used in amplifier applications for pre-amplification purposes, in high-frequency circuits. It is also used as oscillators with its complementary A733 PNP transistor. When used as a switch, it can be easily controlled by an 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 a good choice to use as a switch. 2N2222 will be a better alternative for switching applications.
