Single Zener Diodes Procurement Notes

Verify that the specific part number includes the JANS prefix, which denotes space-grade or high-reliability military qualification under MIL-PRF-19500/406. Confirm package integrity upon receipt, as SQ-MELF components are sensitive to mechanical stress. Ensure compatibility with existing radiation hardening requirements for the target application environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 30 V reference with tight tolerance is required in a ruggedized environment. The SQ-MELF form factor supports automated surface-mount assembly processes. Consider the 1.5 W power rating and 20 Ohm impedance for load regulation needs. Verify that the operating temperature range meets the specific environmental constraints of the deployment scenario.

Single Zener Diodes Part Context

This component belongs to the 1N4476 series of Zener diodes produced by Microchip Technology. It shares functional similarities with other variants like JANTXV1N4476US but differs in qualification level. The JANS designation specifically indicates compliance with stringent military and space-grade standards, distinguishing it from commercial or standard industrial equivalents.
