TIP127 Description

Short technical summary and product information.

The STMicroelectronics TIP127 is a power bipolar junction transistor (BJT) featuring a PNP Darlington configuration. This component is designed for applications requiring high current gain and moderate power handling. It boasts a collector-emitter breakdown voltage of 100V and can handle a continuous collector current of up to 5A.

 

The TIP127 operates at a maximum junction temperature of 150°C, making it suitable for various thermal environments. Its DC current gain (hFE) is a significant 1000 at 3A and 3V, indicating its amplification capabilities. The saturation voltage (Vce) is a maximum of 4V at 20mA and 5A, which is important for switching applications.

 

Packaged in a standard TO-220-3 configuration, the TIP127 is designed for through-hole mounting, facilitating easy integration into printed circuit boards. This package type is common in power applications where heat dissipation is a consideration.

 

This transistor is suitable for use in power supply circuits, audio amplifiers, and general-purpose switching applications where its high gain and current handling are beneficial.
