BD678 Transistor TO126 CDIL 60V 4A PNP Transistors CDIL BD678

Product Overview:

A through-hole PNP silicon Darlington power transistor housed in a TO-126 plastic package. Designed for medium-power linear and switching applications, its Darlington configuration provides an exceptionally high current gain ($h_{FE}$). This makes it ideal for directly driving high-current loads—such as small motors, relays, and solenoids—from low-power logic gates or microcontrollers. It frequently serves as the complementary PNP pair to the BD677 NPN Darlington transistor.
