Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer's part nomenclature to confirm tolerance levels and RoHS compliance status. Ensure that the procurement documentation explicitly references MIL-PRF-19500/117 qualification requirements. Confirm the package type matches the required surface-mount specifications before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 47 V reference is required in a compact surface-mount form factor. Consider the 105 Ohm dynamic impedance for stability requirements. Evaluate the thermal resistance characteristics against the expected operating environment to ensure adequate heat dissipation within the specified junction temperature limits.
