Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required tolerance levels and packaging formats. Confirm RoHS compliance status and lot traceability requirements prior to procurement. Cross-reference the ordering part number with the latest Microchip Technology documentation to validate electrical specifications and mechanical dimensions.

Selection Notes

Select this component when a stable 6.2 V reference with high accuracy is required in space-constrained through-hole designs. The DO-7 package provides robust mechanical mounting compared to smaller surface-mount alternatives. Ensure the circuit design accounts for the 500 mW power dissipation limit and the specific test current conditions defined in the technical data sheet.

Part Context

This device belongs to the standard Zener diode family manufactured by Microchip Technology. It serves as a fundamental discrete semiconductor component for analog circuit design. The product line emphasizes reliability and consistent performance across industrial and commercial temperature ranges, supporting various voltage regulation needs.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4691 variants with matching 6.2 V Zener voltage and ±2% tolerance. Verify that replacement parts maintain the same DO-7 package outline and 500 mW power rating to ensure physical and electrical interchangeability without circuit modification.
