Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Ensure storage conditions meet moisture sensitivity level requirements for lead-free components.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable 18 V reference is required in space-constrained surface-mount designs. The wide operating temperature range makes it suitable for automotive or industrial environments where standard commercial grade parts may fail. Compare the low Zener impedance value against circuit noise requirements to ensure signal integrity is maintained under varying load conditions.

Current Regulation - Diodes, Transistors Part Context

This device belongs to the CDLL53 series of hermetically sealed glass passivated junction Zener diodes. These components are engineered for reliability in demanding applications. The TR suffix indicates tape and reel packaging for automated assembly processes. The series offers consistent performance across the extended temperature range defined by military specifications.

Current Regulation - Diodes, Transistors Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers that match the 18 V Zener voltage and DO-213AA-2 footprint. Verify that substitute devices meet the same 175°C maximum operating temperature and 100 nA leakage current specifications. Ensure the replacement maintains equivalent Zener impedance and power dissipation ratings.
