Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (JAN, JANTX, JANTXV, or JANS) and RoHS compliance status. Confirm the tape and reel packaging specification aligns with manufacturing requirements. Ensure the component meets the necessary environmental screening standards for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode with high reliability qualifications is required. Consider the 19 V nominal voltage and positive temperature coefficient for circuit design. Evaluate the low noise density and minimal capacitance characteristics against system signal integrity requirements.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR-1 through 1N4135UR-1 series of 500 mZener diodes. These components are surface mount equivalents to JEDEC registered axial-leaded series. They offer extensive voltage selection from 1.8 to 100 volts with various tolerance options.

Single Zener Diodes Replacement Considerations

Commercial versions with the CDLL prefix (e.g., CDLL4113-1) are available equivalents. Axial-leaded equivalents include the 1N4113-1 in the DO-35 package. Tabbed surface mount equivalents include the 1PMT4113 in the DO-216 package.
