Description
The TIP120 Series 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).
Features and Applications
Uses: As current amplifiers, audio amplifiers and electronic switches, for example, Motor Drive Amplifiers, Relay Drive Amplifiers.
Data: The TIP 120 series transistors are Darlington Pairs i.e. they have 2 transistors in the one package, which gives them the advantage of higher power handling and gain.
- Voltage between Collector and Emitter 6 - 60 Volts max.
- Power handling capacity 60 Watts max.
- Current handling capacity 5 Amps max.
- Amplification (gain) greater than 1000.
