Overview
The BC849CW is a single NPN general-purpose bipolar junction transistor manufactured by Diotec Semiconductor. It utilizes an SOT-323 surface-mount package and supports a maximum collector current of 100 mA with a power dissipation rating of 200 mW. The device features a collector-emitter breakdown voltage (VCEO) of 30 V, a collector-base voltage (VCBO) of 30 V, and an emitter-base voltage (VEBO) of 5 V. Electrical characteristics include a DC current gain (hFE) ranging from 420 to 800 at IC = 2 mA and VCE = 5 V, a transition frequency (fT) of 100 MHz, and a collector-emitter saturation voltage (VCEsat) of up to 600 mV at IC = 100 mA and IB = 5 mA. Operating temperatures range from -55°C to +150°C.

Procurement Notes
Verify the specific suffix configuration against project requirements before ordering. The 'C' suffix designates commercial grade availability. Confirm that the standard packaging format aligns with assembly line capabilities. Ensure compliance with relevant environmental standards such as RoHS and REACH during component sourcing. Validate datasheet specifications against final application constraints.
Selection Notes
Select this component when a low-voltage NPN transistor with high current gain is required in a compact SOT-323 footprint. The 30 V collector-emitter rating limits suitability for higher voltage environments. Consider the specified hFE ranges to ensure adequate drive capability within the target circuit design parameters.
