Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration when ordering. Confirm the DO-213AA-2 footprint compatibility with your PCB layout constraints. Ensure thermal management strategies account for the 500 mW power dissipation rating under continuous operating conditions. Cross-reference the manufacturer part number with official Microchip documentation to validate revision history and compliance status before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a high-voltage Zener reference is required in a compact surface-mount form factor. The wide operating temperature range makes it suitable for industrial or automotive environments where standard commercial grade parts may fail. Consider the high Zener impedance value when designing for low-current applications, as it may affect regulation accuracy under varying load conditions compared to lower impedance alternatives.

Single Zener Diodes Part Context

This device belongs to Microchip's CDLL series of hermetically sealed glass passivated Zener diodes. These components are engineered for reliability in harsh environments, offering superior stability compared to plastic-packaged equivalents. The series provides various voltage options within a standardized small outline package, facilitating easy integration into space-constrained designs requiring robust voltage referencing capabilities.

Single Zener Diodes Replacement Considerations

Consult official Microchip substitution guides for verified equivalent part numbers. Generic replacements may differ in Zener impedance, leakage current, or thermal characteristics. Verify that any substitute maintains the same DO-213AA-2 package dimensions and pinout configuration to ensure mechanical compatibility without redesigning the printed circuit board assembly.
