Single Zener Diodes Procurement Notes

Verify the specific suffix US/TR against official Microchip documentation to confirm the exact tape-and-reel packaging configuration and quality level. Ensure that the procurement channel provides valid traceability records required for JANS class components. Confirm RoHS status and export control classifications prior to ordering, as these items may be subject to strict regulatory controls.

Single Zener Diodes Selection Notes

Select this component when a 15 V reference is required in a surface-mount form factor within harsh environmental conditions. Compare the 500 mW power rating and 10 Ohm impedance against circuit requirements. Verify that the B-SQ-MELF-2 footprint matches the PCB layout constraints. Consider the -65 C to +175 C range for thermal design margins in enclosed or high-heat assemblies.

Single Zener Diodes Part Context

This part belongs to the 1N6328 series of Zener diodes produced by Microchip Technology under its Microsemi division. The JANS designation indicates a specific quality and radiation-hardened variant intended for space and military applications. It shares electrical characteristics with other 15 V Zener devices but differs in packaging and reliability standards compared to commercial equivalents.
