Single Zener Diodes Procurement Notes

Verify compliance requirements prior to procurement, as this component is explicitly listed as non-RoHS compliant. Confirm that the DO-34 package dimensions and axial lead configuration match the target PCB layout constraints. Ensure the design environment can accommodate the specified 200 °C maximum operating temperature rating during thermal analysis.

Single Zener Diodes Selection Notes

Select this component when a low-noise Zener diode with high thermal endurance is required in an axial glass package. The 0.4 W power rating and 1 µA leakage current define its suitability for specific low-power regulation tasks. Verify that the unidirectional configuration aligns with the circuit's polarity requirements and that the manufacturer designation matches the intended supply chain.

Single Zener Diodes Part Context

This part belongs to the Renesas discrete semiconductor diode portfolio, specifically within the Zener regulator category. It shares the DO-34 package form factor with other variants in the series but is distinguished by its specific 0.4 W power rating and low noise specifications. The component represents a legacy or specialized offering within the broader Renesas discrete device lineup.

Single Zener Diodes Replacement Considerations

Cross-reference with the HZS15-2LTD variant for potential compatibility, noting that both share the DO-34 package and 0.4 W rating. Verify pinout and electrical tolerances against any alternative suppliers offering DO-34 Zener diodes with comparable low noise and high-temperature ratings.
