TIP122G Description

Short technical summary and product information.

The TIP122G from ON Semiconductor is a complementary silicon power transistor featuring a monolithic construction with built-in base-emitter shunt resistors. This NPN Darlington transistor is designed for general-purpose amplifier and low-speed switching applications.

 

Key electrical characteristics include a collector-emitter sustaining voltage of 100V (VCEO(sus)) and a continuous collector current rating of 5A. It offers a high DC current gain (hFE) of 1000 (min) at 3A and 3V, with a typical gain of 2500 at 4A. The saturation voltage (VCE(sat)) is a maximum of 4V at 20mA base current and 5A collector current.

 

This device is housed in a TO-220AB package, suitable for through-hole mounting. It has a maximum power dissipation of 65W at 25°C case temperature and 2W at 25°C ambient temperature. The operating and storage junction temperature range is -65°C to +150°C.

 

The TIP122G is available in Pb-free packages, aligning with environmental considerations for modern electronic designs.
