BD679 Transistor TO126 CDIL 80V 4A NPN DARLINGTON Transistors CDIL BD679

Product Overview: A through-hole NPN 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 (hFE). 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 NPN pair to the BD680 PNP Darlington transistor.
