Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level, as the base part number covers multiple grades. Confirm RoHS compliance status if environmental regulations apply, noting that commercial versions may differ from mil-qualified variants. Ensure the procurement documentation explicitly states the MIL-PRF-19500/435 certification for the intended application.

Single Zener Diodes Selection Notes

Select this component when a 14 V reference with strict ±1% tolerance is required. The DO-35 package provides flexible axial-leaded mounting terminals suitable for through-hole assembly. Consider the low noise density characteristics for sensitive signal paths and verify thermal derating requirements against the expected ambient operating conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mW metallurgically bonded glass Zener diodes. The 'D' suffix indicates a 1% voltage tolerance, distinguishing it from standard 5% or 2% tolerance variants within the same family. These components are designed for applications requiring robust performance under extreme environmental stress.
