The BCX 55-16 E6327 is an NPN silicon audio frequency transistor from the BCX54...BCX56 series, manufactured by Infineon Technologies. It features a collector-emitter voltage (VCEO) of 60 V and a continuous collector current (IC) of 1 A. The device offers a DC current gain (hFE) range of 100 to 250 at IC = 150 mA, with a transition frequency (fT) of 100 MHz. It operates within a junction temperature range of -65 °C to +150 °C and dissipates up to 2 W of power in a SOT89 package.
Verify component authenticity through official Infineon channels or authorized distributors. Confirm RoHS compliance and Pb-free packaging status. Ensure the ordering suffix matches the required tape-and-reel quantity specifications. Validate that the specific batch meets AEC Q101 qualification standards if automotive integration is intended.
Select this component when a 60 V breakdown voltage and 1 A continuous current are required for audio applications. Consider the BCX55-16 variant specifically for its guaranteed hFE range of 100 to 250. Evaluate thermal management requirements given the 2 W power dissipation limit in the SOT89 package.
