Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact electrical tolerances and testing conditions. Ensure compatibility with SMD reflow profiles and check for any RoHS compliance variations in the latest datasheet revisions before finalizing procurement specifications.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 8.25 mA current source is required within a 60 V limit. Consider the 500 mW power dissipation capability and the wide -65°C to +175°C operating range for harsh environments. The DO-213AB package suits space-constrained PCB layouts requiring reliable surface-mount integration.

Current Regulation - Diodes, Transistors Part Context

This part belongs to Microchip's CDLL series of current regulator diodes, designed for applications needing stable current without complex circuitry. The TR suffix indicates tape-and-reel packaging for high-volume manufacturing. It complements standard Zener diodes by offering regulated current rather than voltage reference functionality.

Current Regulation - Diodes, Transistors Replacement Considerations

Consult Microchip's official cross-reference guides for verified substitutes. Generic equivalents may differ in leakage current or voltage tolerance. Verify that alternative parts match the 8.25 mA nominal current and 60 V maximum rating to ensure circuit integrity.
