BC639 Description
The BC639 is a TO-92 packaging NPN transistor with a VCE of 100V and a continuous collector current of 1A. This transistor can be employed in fairly high voltage switching applications with this characteristic and 1W total power dissipation. The BC639 transistor is a very adaptable device that can be used in a wide range of applications. This transistor can be used to switch devices with somewhat high voltages, such as a tiny DC-DC converter or the pre-or mid-amplifier stage of a power amplifier (power amplifiers typically utilize 60 to 120V DC). This transistor could be useful in several situations.
