2N3421 Description

Short technical summary and product information.

The 2N3421 is an NPN bipolar junction transistor manufactured by Microchip Technology. It is designed for general-purpose amplification and switching applications.

 

Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of 80V, a continuous collector current (Ic) of 3A, and a maximum power dissipation of 1W. The DC current gain (hFE) is a minimum of 40 at Ic=1A and Vce=2V, and the Vce saturation voltage is a maximum of 500mV at Ib=200mA and Ic=2A.

 

The transistor is housed in a TO-5 metal can package (TO-205AA) with through-hole mounting. It operates over a junction temperature range of -65°C to 200°C.
