Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N5238BTR designation may be produced by multiple vendors including Microchip Technology or Central Semiconductor. Confirm that the component matches the required DO-35 package dimensions and electrical tolerances before integration. Ensure compliance with RoHS and REACH requirements relevant to your region. Cross-reference datasheets from different suppliers to validate parameter consistency, particularly regarding Zener impedance and leakage current limits.

Single Zener Diodes Selection Notes

Select this component when a standard 8.7 V regulation point is required in through-hole designs. The DO-35 package offers robust mechanical stability compared to surface-mount alternatives. Consider the 5% voltage tolerance and 500 mW power rating to ensure adequate margin for thermal management. Verify compatibility with operating temperatures ranging from -65°C to +200°C if used in extreme environments.
