It is housed in a PG-SC74-6 surface-mount package and supports continuous collector currents up to 500 mA with a maximum power dissipation of 1 W. The device features a collector-emitter voltage rating of 45 V, a collector-base voltage of 50 V, and an emitter-base voltage of 5 V. It exhibits a transition frequency of 170 MHz and operates within a temperature range of -65°C to +150°C. The component is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• High power dissipation capability of 1 W in a compact SC-74-6 package
• Automotive-grade reliability certified under AEC-Q100 standards
• Wide operating temperature range extending to +150°C

Applications

• General-purpose switching circuits in automotive electronics
• Signal amplification in low-power analog applications
• Driver stages for LED arrays or relay control modules

Procurement Notes

Verify the specific suffix configuration against official Infineon documentation to ensure compatibility with design requirements. Confirm that the PG-SC74-6 package dimensions align with PCB footprint specifications. Check current lifecycle status as older variants may be subject to obsolescence notices. Ensure supply chain sources are authorized distributors to guarantee authenticity and traceability of the semiconductor material.

Selection Notes

Select this component when high thermal performance is required in a small form factor. The 1 W dissipation rating distinguishes it from lower-power SOT-23 alternatives. Consider the AEC-Q100 qualification if the application demands automotive-grade robustness. Evaluate the 170 MHz bandwidth to ensure suitability for the intended signal frequencies. Verify that the 45 V voltage rating meets the circuit's maximum operational limits.

Part Context

This part belongs to the BC817 series of NPN transistors, designed for general-purpose amplification and switching. The SUE variant specifically denotes the PG-SC74-6 package, offering enhanced thermal characteristics compared to standard SMD packages. It complements other series members like the BC817K and BC817UPN, which utilize different packaging solutions such as SOT-23-3 and SC-74-6 respectively, catering to diverse space and thermal constraints.

Replacement Considerations

Direct substitutes include BC817SUT and BC817SUP, which share identical electrical parameters and the PG-SC74-6 package. Cross-reference pinout configurations to ensure compatibility during board-level replacement.
