2N4401BU Description

Short technical summary and product information.

The 2N4401BU is an NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications.

 

Key electrical specifications include a collector-emitter breakdown voltage (Vceo) of 40V, a maximum collector current (Ic) of 600mA, and a power dissipation (Pd) of 625mW. The transistor offers a transition frequency (ft) of 250MHz and a minimum DC current gain (hFE) of 100 at 150mA, 1V. The collector-emitter saturation voltage (Vce(sat)) is 750mV maximum at 50mA base current and 500mA collector current.

 

The device is housed in a TO-92-3 through-hole package, suitable for manual insertion and prototyping. It operates over a junction temperature range of -55°C to 150°C. The part is RoHS3 compliant and REACH unaffected with an MSL rating of 1 unlimited.
