Single Zener Diodes Procurement Notes

Verify the specific suffix Q-7-F indicates AEC-Q101 qualification rather than commercial grade. Confirm the SOD-323 case dimensions match the target PCB footprint layout. Ensure the 200 mW power dissipation rating aligns with the thermal management design of the final application environment.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference or clamp is required in space-constrained designs. The SOD-323 package offers a compact form factor suitable for dense surface mount layouts. Consider the 95 Ω impedance value for dynamic load requirements and verify that the 5 µA leakage current meets the low-power standby specifications of the circuit.
