BCW65ALT1G Description

Short technical summary and product information.

The BCW65ALT1G is a general purpose NPN silicon transistor designed for a wide range of low-power amplification and switching applications. Manufactured by On Semiconductor, this device offers a collector-emitter breakdown voltage (VCEO) of 32 V minimum, a collector-base breakdown voltage of 60 V minimum, and a continuous collector current rating of 800 mA. The transistor exhibits a DC current gain (hFE) ranging from 100 to 250 at Ic=100 mA, Vce=1.0 V, with a maximum collector-emitter saturation voltage of 700 mV at Ib=50 mA, Ic=500 mA.

 

The device is available in a surface-mount SOT-23 (TO-236) package, making it suitable for compact PCB designs. It supports an operating and storage junction temperature range of -55°C to +150°C. Power dissipation is rated at 225 mW on an FR-5 board and 300 mW on an alumina substrate, with corresponding thermal resistances of 556°C/W and 417°C/W respectively.

 

The BCW65ALT1G is part of On Semiconductor's Pb-Free, Halogen Free/BFR Free product line and is RoHS compliant. The suffix 'G' in the part number indicates Pb-Free construction. It is supplied in tape and reel packaging with 3000 units per reel, suitable for automated assembly processes.
