TIP122 Transistor: Datasheet, Dimension, and Circuit

The TIP122 is a NPN Darlington Power Transistor. It is manufactured in planar technology with "base island" layout and monolithic Darlington configuration.It can switch loads up to 60V with a peak current of 8A and continuous current of 5A. This makes it suitable for medium and high power electronics like controlling motors, solenoids or high power LEDs.

This transistor is known for its high current gain (hfe = 1000) and high collector current (IC =5A) hence it is normally used to control loads with high current or in applications where high amplification is required. This transistor has a low Base-Emitter Voltage of the only 5V hence can be easily controlled by Logic devices like microcontrollers. Although care has to be taken to check if the logic device can source up to 120mA.

So, if you looking for a transistor that could be easily controlled by a Logic device to switch high power loads or to amplify high current then this Transistor might be an ideal choice for your application.

• Can be used to switch high current (upto 5A) loads

• Can be used as medium Power switches

• Used where high amplification is needed

• Speed control of Motors

• Inverter and other rectifier circuits
