Procurement Notes

Verify the specific suffix '-1' against official Microchip documentation to confirm exact mechanical or environmental specifications, as suffixes often denote distinct packaging or reliability grades. Ensure the required operating temperature range aligns with the component's rated limits. Cross-reference datasheet parameters such as Zener impedance and leakage current with system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a precise 6.8 V regulation point is required within a through-hole design. The ±5% tolerance makes it suitable for general-purpose regulation where tighter tolerances are unnecessary. Consider the 500 mW power rating to ensure adequate heat dissipation in the target application environment. Verify that the DO-35 package dimensions fit the available PCB space.
