Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm the exact package type and marking code. Confirm RoHS compliance status and AEC-Q101 automotive qualification requirements for your specific application environment before finalizing procurement specifications.

Selection Notes

Select this component when a compact NPN digital switch with a 4.7 kΩ internal base resistor is required. Ensure the operating voltage does not exceed 50 V and the continuous current remains within 100 mA limits. Consider thermal derating curves if the ambient case temperature exceeds 102°C to maintain safe power dissipation levels.
