• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS reliability levels
• Low noise density performance suitable for precision regulation applications

Single Zener Diodes Applications

• High-reliability aerospace and defense circuits
• Precision voltage reference regulation
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple qualification grades. Confirm RoHS compliance status if environmental regulations apply, noting that RoHS versions are typically commercial grade only. Ensure the 'TR' suffix is correctly specified for tape and reel delivery requirements.

Single Zener Diodes Selection Notes

Select this component when a 10 V Zener voltage with tight 1% tolerance is necessary for surface mount designs. The DO-213AA package provides a hermetic seal beneficial for harsh environments. Consider the 500 mW power rating and thermal derating characteristics for circuit layout planning.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR-1 through 1N4135UR-1 series of 500 mW metallurgically bonded glass surface mount Zener diodes. These components serve as surface mount equivalents to standard axial-leaded JEDEC registered Zener diodes, offering high reliability for demanding industrial and military applications.

Single Zener Diodes Replacement Considerations

Commercial equivalents include CDLL4104-1. Axial-leaded alternatives in the same family are 1N4104-1. Verify pinout compatibility and thermal resistance differences when substituting packages.
