BD434 Description

Short technical summary and product information.

The BD434 is a PNP bipolar junction transistor (BJT) manufactured by STMicroelectronics. It is designed for general purpose amplification and medium-power switching applications.

 

Key electrical ratings include a collector-emitter voltage (Vceo) of 22V, collector current (Ic) of 4A, and a power dissipation of 36W. The device exhibits a DC current gain (hFE) of minimum 40 at Ic=10mA, Vce=5V, and a maximum collector-emitter saturation voltage of 500mV at Ib=200mA, Ic=2A. The transition frequency (fT) is 3MHz, making it suitable for audio and low-frequency switching circuits.

 

The BD434 is supplied in a through-hole SOT-32-3 package, also referenced as TO-225AA or TO-126-3. It operates at a junction temperature up to 150°C.
