2N2642 Description

Short technical summary and product information.

The 2N2642 is a silicon bipolar transistor manufactured by STMicroelectronics. It is designed for general-purpose applications and comes in a TO-18 package.

 

Key electrical characteristics include a collector-emitter breakdown voltage (Vceo) of 45V and a collector-base breakdown voltage (Vcbo) of 45V. The maximum collector current (Ic max) is 300mA, with a typical collector current (Ic) for measurement of 30mA. The device has a minimum current gain (h21e) of 31 and a minimum transition frequency (fT) of 30MHz. The maximum power dissipation (Pc max) is 300mW.

 

This transistor is suitable for use in low-power switching and amplification circuits. Its TO-18 metal can package allows for efficient heat dissipation in moderate power applications.
