• Qualified according to AEC-Q101 for automotive applications

Single Zener Diodes Applications

• Low-current general regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q101 qualification status. Confirm the 'C' designation corresponds to the approximate ±5% tolerance series rather than the tighter ±2% variant. Ensure the ordering part number matches the required voltage marking code '1F' for the 2.2 V specification.

Single Zener Diodes Selection Notes

Select this component for designs requiring ultra-small footprint regulation in high-density circuits. The low test current specification makes it suitable for energy-efficient systems. Verify thermal constraints on the PCB copper area to ensure safe operation within the 300 mW dissipation limit.
