TIP127 Description

Short technical summary and product information.

The TIP127 is a power bipolar junction transistor (BJT) from ON Semiconductor, specifically a PNP Darlington type. It is designed for applications requiring high current gain and moderate power handling. This transistor features a maximum collector-emitter voltage of 100V and can handle a continuous collector current of up to 5A.

 

With a DC current gain (hFE) of 1000 minimum at 3A and 3V, the TIP127 is suitable for amplification tasks. Its saturation voltage (Vce Sat) is a maximum of 4V at 20mA and 5A, indicating its suitability for switching applications. The device is rated for 2W of power dissipation and operates within a junction temperature range of -65°C to 150°C.

 

The TIP127 is packaged in a standard TO-220-3 configuration, facilitating through-hole mounting on printed circuit boards. This package type is common in power applications due to its thermal dissipation capabilities and ease of assembly.

 

Compliance information indicates RoHS3 compliance, MSL 1, and REACH unaffected status, though these are noted with low confidence due to unverified data.
