TIP122 NPN Power Transistor

The TIP122 NPN Power Transistor is a Darlington pair transistor capable of switching higher current loads up to 5A. It is ideal for driving motors, solenoids, relays, and other power-hungry DC loads from microcontroller outputs.

Key Features

NPN Darlington pair
High current capability (5A max)
High gain (hFE: 1000+)
TO-220 package for heatsink mounting
100V VCEO rating
Built-in base-emitter resistors
Logic-level drivable from 5V MCU

Technical Specifications

Parameter	Specification
Type	NPN Darlington
Max VCEO	100V
Max IC	5A
Power Dissipation	65W (with heatsink)
hFE (gain)	1000 minimum
Package	TO-220
VCE(sat)	~2V at 3A

Applications

Motor driving
Solenoid control
Relay driving
High-current LED arrays
Power switching
Linear regulators

Important Notes

Heatsink REQUIRED for currents above 1A
High VCE(sat) means significant heat at high current
Consider MOSFET for better efficiency in switching applications
Built-in snubber diodes not included – add for inductive loads
TO-220 tab is connected to collector – insulate if needed
