BC848BE6433HTMA1

Overview

The BC848BE6433HTMA1 is an NPN silicon small-signal bipolar junction transistor (BJT) manufactured by Infineon Technologies. It operates in a single configuration within a surface-mount SOT-23-3 package. The device supports a maximum DC collector current of 100 mA and withstands a collector-emitter voltage of 45 V, with a collector-base voltage rating of 50 V. Key electrical characteristics include a transition frequency of 250 MHz, a power dissipation capacity of 330 mW, and a collector-emitter saturation voltage of 200 mV. It functions reliably across a temperature range from -65°C to +150°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for enhanced reliability
• High-frequency performance optimized for audio frequency applications via specified transition frequency
• Low saturation voltage design facilitates efficient switching and signal amplification
• Compact surface-mount packaging enables integration into space-constrained circuit boards

Applications

• General-purpose amplification in consumer electronics
• Switching circuits requiring automotive-grade component reliability
• Audio frequency signal processing stages
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix HTMA1 against official Infineon documentation to confirm exact binning and tape-and-reel specifications. Confirm current lifecycle status as distribution channels may list obsolete or end-of-life variants. Ensure compatibility with RoHS directives if required by target market regulations. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when an NPN transistor with 45 V collector-emitter breakdown is required for robust operation. The AEC-Q100 qualification makes it suitable for automotive environments where standard commercial parts may fail. Compare the 200 mV saturation voltage against alternatives if minimizing power loss in switching applications is critical. Verify that the SOT-23-3 footprint matches the existing PCB layout constraints.

Part Context

This part belongs to the BC848 series of small-signal NPN transistors produced by Infineon Technologies. The BC848 family is widely recognized for general-purpose amplification and switching tasks. The specific model integrates automotive quality assurance, distinguishing it from standard commercial variants while maintaining similar electrical footprints and pinouts common to the SOT-23 form factor.

Replacement Considerations

Consult official Infineon substitution guides for verified equivalents. Generic replacements must match the 45 V VCEO rating and SOT-23-3 package. Verify that substitute components meet AEC-Q100 requirements if automotive application integrity is mandatory.
