The '''BFY51''' Collector is connected to the positive (+ve) supply via the load. NB If the load is inductive i.e. has coil windings such as a relay, solenoid or motor, then it is usual to connect a diode across it to prevent the Back EMF from damaging the transistor. (Cathode to supply). The input is connected to the Base via a limiting resistor (typically 1K). The Emitter is connected to the negative (-ve) supply (0V).


'''Uses:''' As current amplifiers and electronic switches, for example, Motor Drive Amplifiers, Audio Amplifiers.


'''Data:''' Voltage between Collector and Emitter 6 - 30Volts max.
* Power handling capacity 800mWatts max.
* Current handling capacity 1 Amp max.
* Amplification (gain) greater than 50.
