Procurement Notes
Verify the specific ordering code suffix against official documentation to confirm packaging quantity and reel specifications. Ensure that the component meets the required AEC-Q101 qualification standards for the intended application environment. Cross-reference the manufacturer's datasheet revision history to validate current production status and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required for space-constrained designs. The ±5% voltage tolerance suits general-purpose regulation tasks. Verify that the operating junction temperature remains within the specified -55 °C to +150 °C range under all expected thermal conditions. Confirm compatibility with standard surface-mount reflow soldering profiles.
