- AEC-Q100 qualified for automotive reliability standards
- High DC current gain ranging from 250 to 630
- Wide operating temperature range up to 150°C
- Compact SOT-23-3 surface-mount packaging
Applications
- Automotive signal switching circuits
- General-purpose amplification stages
- Low-power digital logic interfacing
Procurement Notes
Verify the specific suffix HE6327HTSA1 against official Infineon documentation to confirm tape-and-reel quantities and RoHS compliance status. Confirm end-of-life or obsolescence status directly with the manufacturer, as distributor listings may indicate discontinuation. Ensure the component meets AEC-Q100 requirements if used in automotive designs by checking the latest datasheet revision.
Selection Notes
Select this component when a high-gain NPN transistor is required in a compact SOT-23-3 footprint for automotive or industrial environments. The 45 V rating suits low-voltage signal processing. Compare the 170 MHz transition frequency against application bandwidth needs. Verify thermal management capabilities given the 500 mW dissipation limit in small packages.
Part Context
This part belongs to the BCW66 series of general-purpose NPN transistors designed for audio frequency and switching applications. The series is known for high linearity and gain consistency. The specific suffix indicates automotive-grade screening and standard reel packaging formats suitable for automated surface-mount assembly processes.
Replacement Considerations
Check for direct pin-compatible alternatives within the BCW66 family, such as BCW66KGE6327HTSA1, ensuring gain ranges match design requirements. Verify that any substitute maintains AEC-Q100 qualification and identical SOT-23-3 mechanical dimensions for board compatibility.
