SunRobotics BC848 sot23 NPN 3 pin SMD General Purpose Transistor 50Pcs NPN Transistor  (Number of Transistors 50)

BC847 is an NPN transistor so when no power is applied to the base, the collector and emitter will be left open (Reverse biased) and when a positive voltage is applied to the base pin, the transistor will turn on. This transistor is the SMD equivalent for the popular BC547/BC847 transistor, which is commonly used in many general-purpose applications like switching circuits to control low current loads like pumps, solenoids, LEDs, etc. The transistor also has an equivalent PNP transistor called BC557/BC957, both combined can be used to form push-pull circuits or Class B amplifier Designs.
