BD533 Description

Short technical summary and product information.

The BD533 is an NPN power transistor manufactured by STMicroelectronics using Planar technology with Base Island layout, offering high gain performance and very low saturation voltage.

 

Key electrical ratings include a collector-emitter voltage of 45V (VCEO), continuous collector current of 8A, and total power dissipation of 50W at 25°C case temperature. The device features a typical DC current gain (hFE) of 25 minimum at 2A collector current and low VCE saturation voltage of 0.8V max at 6A.

 

The transistor comes in the standard through-hole TO-220-3 package, making it suitable for general-purpose power switching and amplification circuits. Operating junction temperature range extends to 150°C.
