Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm compliance with environmental directives such as RoHS or REACH status directly with the manufacturer, as these attributes may vary based on production batches and specific ordering codes.

Single Zener Diodes Selection Notes

Select this component when circuit requirements demand low noise performance and minimal leakage current. Ensure the 250 mW power rating is sufficient for the expected thermal environment. Verify that the 27 V nominal voltage aligns with the target regulation point and that the DO-35 through-hole package fits the board layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N4099 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 6.8 V to 100 V, all sharing similar low-noise characteristics and 5% tolerance specifications. These devices are intended for general-purpose voltage regulation where stability and low interference are critical design factors.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4118 equivalents in the DO-35 package. Verify that substitute parts meet the same 250 mW power dissipation, 27 V nominal voltage, and low noise density specifications to ensure functional compatibility.
