Description
The TIP122 is a Darlington pair NPN transistor. It functions like a normal NPN transistor, but since it has a Darlington pair inside it has a good collector current rating of about 5A and a gain of about 1000. It can also withstand about 100V across its collector- Emitter hence can be used to drive heavy loads.
Features
Darlington Medium-power NPN Transistor High DC Current Gain (hFE), typically 1000 Continuous Collector current (IC) is 5A Collector-Emitter voltage (VCE) is 100 V Collector-Base voltage (VCB) is 100V Emitter Base Voltage (VBE) is 5V Base Current(IB) is 120mA
