2N3902 Description

Short technical summary and product information.

The 2N3902 is an NPN bipolar junction transistor manufactured by Microchip Technology. It is designed for general-purpose switching and linear amplification applications requiring high voltage handling capability.

 

Key electrical specifications include a collector-emitter voltage (Vceo) of 400V, a collector current (Ic) of 3.5A, and a power dissipation of 5W. The minimum DC current gain (hFE) is 30 at 1A collector current and 5V collector-emitter voltage, and the maximum collector-emitter saturation voltage is 2.5V at a base current of 700mA and collector current of 3.5A.

 

The transistor is housed in a TO-204AA (TO-3) through-hole package, compatible with the TO-204AD (TO-3) supplier device package. It operates over a junction temperature range of -65°C to 200°C, making it suitable for demanding environments. The through-hole mounting allows for robust mechanical attachment and thermal management.
