2N4403 Description

Short technical summary and product information.

The 2N4403 is a general purpose PNP bipolar junction transistor manufactured by Diotec Semiconductor. It is designed for signal processing, switching, and amplification applications in commercial and industrial grade equipment.

 

Key electrical characteristics include a collector-emitter voltage (VCEO) of 40V, collector-base voltage (VCBO) of 40V, emitter-base voltage (VEBO) of 5V, and a continuous collector current (IC) rating of 600mA. The device can dissipate up to 625mW of power. DC current gain (hFE) ranges from 30 to 300 depending on test conditions, with a typical gain of 100 at 150mA. The transition frequency (ft) is 200MHz, making it suitable for low to medium frequency applications.

 

The transistor is housed in a TO-92 through-hole package (TO-226-3, TO-92-3) with a weight of approximately 0.18g. The case material is UL 94V-0 rated. It is supplied in ammo pack packaging with a standard quantity of 4000 units. The device is compliant with RoHS, REACH, and Conflict Minerals regulations. The complementary NPN transistor is the 2N4401.
