Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix (e.g., /TR) against official Microchip documentation to confirm packaging configuration. Ensure the DO-213AB MELF package dimensions align with PCB layout requirements. Cross-reference the 902 µA current rating and 100 V breakdown voltage with circuit design specifications to prevent operational mismatch.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required in a small form factor. The 500 mW power rating supports moderate load conditions. Consider the 1 µA leakage limit for high-impedance applications. The wide temperature range makes it suitable for harsh environments where standard commercial-grade diodes may fail.

Current Regulation - Diodes, Transistors Part Context

This part belongs to Microchip's CDLL series of Zener diodes, specifically optimized for current regulation rather than simple voltage clamping. It complements other MELF-form-factor components in the portfolio, offering robust performance in space-constrained designs requiring reliable DC current sources.

Current Regulation - Diodes, Transistors Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements must match the 902 µA current tolerance, 100 V breakdown, and DO-213AB package constraints to ensure functional compatibility.
