Procurement Notes
Verify the specific suffix 'AQ' against official Diotec documentation to confirm AEC-Q101 compliance and automotive grade status. Ensure the SOT-323 package matches the design requirements. Cross-reference datasheet parameters such as hFE ranges and thermal characteristics with the latest manufacturer release to avoid discrepancies.
Selection Notes
Select this component when automotive qualification is mandatory for low-power NPN switching or amplification tasks. The SOT-323 form factor offers a smaller footprint compared to standard SOT-23 packages. Consider the 200 mW power dissipation limit and 100 mA current capacity during circuit design to ensure operation within safe limits.
