BD682 Transistor TO-126 BD682

The BD682 is a versatile NPN Darlington transistor housed in the TO-126 package, designed for medium-power linear and switching applications. This transistor is known for its high current gain and robust performance, making it a reliable choice for driving relays, solenoids, and other inductive loads. The Darlington configuration consists of two BJTs (Bipolar Junction Transistors) connected in such a way that the current amplified by the first transistor is further amplified by the second, resulting in a very high current gain. This high gain allows the BD682 to be driven directly by low-current signals from microcontrollers or logic gates. Key specifications of the BD682 include a collector-emitter voltage (VCEO) of 100V, a collector current (IC) of 4A, and a power dissipation (PD) of 40W. Its high current gain (hFE), typically ranging from 750 to 2000, enables it to switch or amplify signals with minimal base current.

The TO-126 package provides good thermal conductivity, allowing the transistor to dissipate heat efficiently. This transistor is frequently used in motor control circuits, where it can drive small DC motors or stepper motors. In power supply circuits, it can be used as a switching element or regulator.
