2N3904-AP Description

Short technical summary and product information.

The 2N3904-AP is an NPN bipolar junction transistor designed for general purpose amplifier and switching applications. It is housed in a through-hole TO-92 package (TO-226-3, TO-92-3 (TO-226AA) formed leads) and is supplied by Micro Commercial.

 

Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 40V, a maximum collector-base voltage (VCBO) of 60V, and a maximum emitter-base voltage (VEBO) of 6V. The device supports a continuous collector current of 200mA and dissipates up to 625mW. DC current gain (hFE) ranges from a minimum of 100 at 10mA to a minimum of 30 at 100mA, with a transition frequency of 250MHz.

 

The transistor offers low saturation voltages, such as 0.2V at 10mA collector current, and a typical noise figure of 5dB, making it suitable for low-level signal amplification. Switching times include a typical delay time of 35ns, rise time of 35ns, storage time of 200ns, and fall time of 50ns.

 

The 2N3904-AP operates over a junction temperature range of -55°C to +150°C and has a thermal resistance of 200°C/W junction-to-ambient. The device is lead-free and RoHS compliant, with an epoxy that meets UL 94 V-0 flammability rating.
