Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required military standards. Confirm that the TR designation aligns with tape-and-reel handling requirements for your assembly line. Cross-reference the MIL-PRF-19500/115 compliance status directly with the manufacturer's latest quality certifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and wide temperature operation are critical. The DO-213AA-2 package offers a compact footprint for space-constrained PCB layouts. Ensure design margins account for the 6 Ohm dynamic impedance to maintain signal integrity under varying load conditions in sensitive analog applications.

Single Zener Diodes Part Context

This part belongs to the JANTX series of Zener diodes, which are engineered for enhanced reliability compared to commercial grades. The CUR-1 suffix indicates a specific reel packaging format within the Microchip portfolio. These devices are integral to maintaining stable reference voltages in harsh operational environments where standard components may fail.

Single Zener Diodes Replacement Considerations

JAN1N3019D-1/TR serves as a parameter-equivalent through-hole alternative. JANTX1N3019D-1 provides a similar specification without the reel packaging. Verify pinout compatibility and package dimensions when substituting surface mount variants with axial lead equivalents.
