Single Zener Diodes Procurement Notes

Verify that the specific suffix 'US' corresponds to the required surface mount package type and lead-free status if mandated by your assembly process. Confirm that the JANTX grade meets your specific reliability requirements, as it differs from JAN or JANS levels. Ensure compatibility with your PCB footprint design for the SQ SMT package before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for MIL-PRF-19500/406 compliance. The JANTX grade offers tighter testing than JAN but may differ in cost and availability compared to JANS. Consider the physical dimensions of the SQ SMT package against your board space constraints and verify thermal management needs for the intended power dissipation level.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5-watt glass Zener diodes. These components are industry-recognized regulators available in various voltage selections with standard tolerances. The series provides a direct surface mount alternative to traditional through-hole equivalents, maintaining the same electrical characteristics while enabling automated assembly processes for modern manufacturing lines.

Single Zener Diodes Replacement Considerations

Direct replacements include other JANTX1N4469 variants or equivalent MIL-PRF-19500/406 qualified Zener diodes from authorized manufacturers. Verify pinout compatibility and package dimensions when substituting with non-Microchip parts to ensure mechanical fit.
