The STMicroelectronics TIP121 is a versatile NPN Epitaxial Darlington Transistor suitable for medium power linear switching applications. It offers a robust design with a Collector-Emitter Voltage (VCEO) of 80V and a continuous Collector Current (IC) of 5A.
Key electrical characteristics include a high DC Current Gain (hFE) of 1000 at 3A, and a Collector-Emitter Saturation Voltage (VCE(sat)) of up to 4V at 5A. The transistor operates within a junction temperature range of -65°C to 150°C and has a power dissipation of 65W when mounted on a heatsink.
This component is packaged in a standard TO-220-3 configuration, designed for through-hole mounting. Its complementary nature to the TIP125, TIP126, and TIP127 series makes it a flexible choice for various circuit designs.
The TIP121 is well-suited for applications requiring amplification or switching of moderate power levels, such as power supply regulation, motor control, and audio amplifiers.
