2N3904TAR Description

Short technical summary and product information.

The 2N3904TAR is a general-purpose NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for low-power amplification and switching applications. Key electrical characteristics include a minimum collector-emitter breakdown voltage (Vceo) of 40V, a maximum collector current (Ic) of 200mA, and a maximum power dissipation (Pd) of 625mW. The device offers a typical transition frequency (fT) of 300MHz, making it suitable for moderate-speed switching and amplification up to VHF frequencies. The minimum DC current gain (hFE) is 100 at a test condition of Ic=10mA and Vce=1V, with a maximum Vce saturation voltage of 300mV at Ib=5mA and Ic=50mA. The transistor is housed in a TO-92-3 (TO-226AA) package with formed leads, designed for through-hole mounting. It supports an operating junction temperature range of -55°C to 150°C.
