TIP122 Darlington NPN Power Transistor 100V 5A TO-220

The TIP122 Darlington NPN Power Transistor is a high-gain semiconductor component designed for electronic switching, load control, and power amplification applications. Its Darlington configuration provides high current gain, allowing a relatively small base current to control a larger collector current.

With a collector-emitter voltage rating of up to 100V and a maximum collector current rating of 5A, the TIP122 is suitable for compatible motor control circuits, relay drivers, solenoid switching, LED control, and various power electronics projects.

The TIP122 Darlington Transistor comes in a standard TO-220 through-hole package, making it convenient to install in electronic circuits, prototyping boards, and custom PCBs. It is widely used by electronics enthusiasts, engineering students, repair technicians, and embedded systems developers.

The TIP122 NPN Transistor can be controlled by microcontroller-based circuits when an appropriate base-driving circuit and current-limiting resistor are used. Its relatively high saturation voltage should be considered when designing power switching circuits.
