Description
The TIP122 is a high-performance NPN Darlington pair transistor, designed to deliver exceptional current gain and robust load-driving capability. With a high gain value of 1000, this device is engineered to amplify low-level control signals into significant current, making it an ideal choice for high-sensitivity control circuits that require reliable power switching.
Built to handle a collector current of up to 5A, the TIP122 is perfectly suited for power-intensive applications such as motor control, heavy-duty relay switching, and high-current solenoid drivers. Its Darlington architecture ensures efficient switching performance even with very low input current. Rated for a maximum junction temperature of 150°C, this transistor provides the durability required for industrial power management. This pack of 4 units is an excellent, cost-effective solution for your inventory, prototyping, or specialized power-electronics repair projects.
