BD235 Description

Short technical summary and product information.

The BD235 is a low voltage NPN power transistor manufactured by STMicroelectronics using Planar technology with a Base Island layout. This design provides exceptionally high gain and very low saturation voltage. The transistor is rated for a maximum collector-emitter voltage (VCEO) of 60V and a collector current (IC) of up to 2A (peak 6A). DC current gain (hFE) is a minimum of 25 at VCE=2V, IC=1A. Collector-emitter saturation voltage is typically 0.6V maximum at Ib=100mA, Ic=1A.

 

Power dissipation is rated at 25W at a case temperature of 25°C, with a maximum junction temperature of 150°C. The device is housed in a through-hole SOT-32 package (also known as TO-225AA or TO-126-3). It is suitable for audio, power linear, and switching applications. The BD235 is RoHS3 compliant (unverified) and has an MSL rating of 1 (unlimited).
