TIP31 Description

Short technical summary and product information.

The TIP31 is a silicon NPN power transistor manufactured by ON Semiconductor, designed for versatile use in general purpose amplifier and switching applications. It offers a collector-emitter voltage (VCEO) of 40V and can handle a continuous collector current (IC) of up to 3A, with a peak current capability of 5A.

 

This transistor is housed in a standard TO-220-3 package, facilitating through-hole mounting. Key electrical characteristics include a DC current gain (hFE) of 10 at 3A and 4V, and a Vce saturation voltage of 1.2V at 375mA and 3A. The operating frequency is up to 3MHz.

 

With a total power dissipation rating of 2W at 25°C ambient temperature, the TIP31 is suitable for moderate power applications. The operating temperature range is from -65°C to 150°C (TJ).
