BC640 Transistor CDIL BC640

Product Overview:

A through-hole PNP silicon bipolar junction transistor housed in a standard TO-92 plastic package. Designed for medium-power amplification and switching, it is commonly used in audio amplifier output stages, load drivers, and general-purpose circuits requiring higher current handling than standard small-signal transistors. It frequently serves as the complementary PNP pair to the BC639 NPN transistor.
