BD440 Description

Short technical summary and product information.

The BD440 is a PNP power transistor manufactured by STMicroelectronics using Planar technology with an "Base Island" layout. This design results in high gain performance and low saturation voltage. It is suitable for linear and switching applications in industrial equipment.

 

Key electrical specifications include a collector-emitter voltage of -60V, a collector current of -4A, and a collector peak current of -7A. The device has a maximum power dissipation of 36W at Tcase = 25°C and an operating junction temperature up to 150°C. Saturation voltage is typically -0.8V at IC = -2A and IB = -0.2A.

 

The BD440 is available in a SOT-32 package and is supplied in tubes. It is designed for through-hole mounting.

 

This transistor is the PNP complement to the NPN types BD439 and BD441.
