2N4033 Description

Short technical summary and product information.

The Central Semiconductor Corp 2N4033 is a PNP silicon transistor manufactured using the epitaxial planar process. It is designed for high current general purpose amplifier applications.

Key electrical specifications include a collector-emitter voltage (VCEO) of 80V and a continuous collector current (IC) of 1.0A. The device offers a maximum power dissipation of 1.25W at ambient temperature and 7.0W at 25°C case temperature. Thermal resistance is 140°C/W junction-to-ambient and 20°C/W junction-to-case.

Electrical characteristics include a DC current gain (hFE) ranging from 100-300 at IC=100mA and a transition frequency (fT) of 100-400 MHz. Saturation voltages are specified, with VCE(SAT) at 0.15V maximum for IC=150mA, IB=15mA.

The transistor is housed in a TO-39 case and is suitable for through-hole mounting. Operating and storage junction temperatures range from -65°C to +200°C.
