• Automotive-grade reliability ensured through AEC-Q100 qualification standards.
• High thermal stability supports operation in demanding industrial environments.

Applications

• General-purpose switching circuits in automotive electronics
• Driver stages for low-power loads requiring simplified biasing
• Logic level translation interfaces in embedded systems

Procurement Notes

Verify the specific ordering suffix E6433 against official Infineon documentation to confirm the exact tape-and-reel configuration and manufacturing lot details. Confirm end-of-life status with the manufacturer prior to finalizing procurement plans, as discontinuation notices may affect long-term supply availability.

Selection Notes

Select this component when a single NPN digital transistor with a 4.7 kOhm base resistor is required. Ensure the application voltage does not exceed 50 V and current remains below 100 mA. Verify that the SOT-23-3 footprint matches the PCB design constraints and that the operating temperature range aligns with system requirements.

Part Context

This part belongs to the BCR116 series of NPN digital transistors. It shares the same core transistor characteristics with other variants in the family but differs in its integrated resistor network values and packaging suffix. The E6433 suffix denotes a specific production version within Infineon's discrete semiconductor portfolio.

Replacement Considerations

BCR116E6327HTSA1 is a documented alternative variant within the same series offering similar electrical performance. Verify pin compatibility and resistor values before substitution.
