BD440 Description

Short technical summary and product information.

The BD440 from Telefunken is a PNP power transistor manufactured using Planar technology with a “Base Island” layout. This design results in high gain performance and low saturation voltage.

 

Key electrical specifications include a maximum collector-base voltage (VCBO) of -60V and a maximum collector current (IC) of -4A. The device can handle a collector peak current (ICM) of -7A and a base current (IB) of -1A. Its total power dissipation (PTOT) at Tcase = 25°C is 36W, with a maximum operating junction temperature (TJ) of 150°C.

 

Electrical characteristics include a collector-emitter sustaining voltage (VCEO(sus)) of -60V and a collector-emitter saturation voltage (VCE(sat)) of -0.8V at IC = -2A and IB = -0.2A. The DC current gain (hFE) is typically 20 at IC = -10mA, 40 at IC = -500mA, and 25 at IC = -2A.

 

The BD440 is supplied in a SOT-32 package and is suitable for through-hole mounting. It is intended for applications in linear and switching industrial equipment.
