FULL DESCRIPTION

This complete 30-piece electronic component kit from Youmile features TIP120 NPN Darlington bipolar power transistors paired with 2.2k Ohm resistors and 1N4001 rectifier diodes. Housed in durable TO-220 through-hole packages, the TIP120 Darlington transistor is designed for high-gain power switching and amplification projects, supporting up to 60V collector-emitter voltage and 5A continuous collector current. The high gain of the Darlington pair allows microcontrollers such as Arduino, Raspberry Pi, and ESP32 to easily trigger heavy electrical loads, including solenoids, DC motors, high-power LEDs, relays, and pumps. The included 2.2k Ohm base resistors protect microcontroller I/O pins, while the 1N4001 flyback diodes safeguard circuit components against inductive voltage spikes.

KEY FEATURES

• TIP120 Darlington power transistors — 30 NPN transistors rated for 60V and 5A collector current

• Complete driver kit — includes matching 2.2k Ohm base resistors and 1N4001 flyback protection diodes

• High gain power switching — allows low-current microcontroller pins to switch heavy high-current loads

• Standard TO-220 through-hole package — easy to insert into solderless breadboards or PCB prototype boards

• Flyback voltage spike protection — 1N4001 diodes protect sensitive ICs from inductive kickback from motors and coils

• Ideal for Arduino & DIY electronics — perfect for driving DC motors, solenoids, LED strips, relays, and pumps
