About this product
BD649 is an NPN Darlington power transistor rated 100 V and 8 A, with power dissipation up to 62.5 W in a TO-220 package. Its high current gain lets a small base current control larger loads, such as relays, solenoids and motor drivers. Its complementary PNP partner is the BD650.

How should I protect the BD649 when driving relays or solenoids?
Inductive loads produce voltage spikes when switched off. Place a flyback diode across the coil, with its cathode toward the supply, to protect the transistor.
Is the BD649 suitable for fast switching?
Darlington transistors switch more slowly than single transistors because of their internal structure. They suit driving loads and power stages more than high-frequency switching.
