The BC850CWE6327HTSA1 is a single NPN silicon bipolar junction transistor manufactured by Infineon Technologies. It is housed in a surface-mount SOT-23-3 package with two leads. The device supports a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. Key electrical parameters include a DC current gain (hFE) range of 200 to 450, a transition frequency of 250 MHz, and a power dissipation rating of 330 mW. It operates within a temperature range of -65 °C to +150 °C.
Verify the specific hFE binning (C grade: 200-450) against circuit requirements. Confirm the SOT-23-3 footprint compatibility during PCB layout. Check for RoHS compliance documentation. Ensure storage conditions meet moisture sensitivity level standards. Validate that the 330 mW power dissipation limit is sufficient for the intended thermal environment.
Select this component when a moderate-gain NPN transistor is required in a small form factor. Compare against BC850B if lower gain thresholds are acceptable. Consider thermal management strategies given the 330 mW dissipation limit. Verify voltage ratings align with the maximum supply voltages in the target application circuit.
This part belongs to the BC850 series of general-purpose NPN transistors from Infineon. It shares the same physical package and basic structure as variants like BC850B but differs in current gain specifications. The 'WE6327HTSA1' suffix indicates specific tape-and-reel packaging and manufacturing lot details.
BC850B E6327 is a documented alternative within the same family, offering similar electrical characteristics with potentially different gain binning.
