Single Zener Diodes Procurement Notes

Verify the specific suffix BE3/TR against official Microchip documentation to confirm compliance with RoHS directives and tape-and-reel packaging specifications. Ensure that the ordering quantity aligns with the manufacturer's standard reel pack size requirements. Cross-reference the part number with the latest datasheet to validate electrical parameters before integration into final designs.

Single Zener Diodes Selection Notes

Select this component when a precise 180 V regulation point is required with tight tolerance constraints. The high junction temperature rating allows operation in thermally demanding environments without derating. Consider the significant Zener impedance value when designing for low-current stability or noise-sensitive signal paths.

Single Zener Diodes Part Context

This device belongs to the standard 1N52xx series of silicon planar Zener diodes manufactured by Microchip Technology. The series offers a broad spectrum of voltage ratings from low to high values, all sharing common mechanical dimensions and thermal characteristics. The 1N5279 variant specifically addresses the need for higher voltage regulation capabilities within this established product family.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N5279B and 1N5279A variants, which share identical electrical specifications but differ in voltage tolerance and package style. Verify compatibility with existing PCB footprints and regulatory compliance requirements when transitioning between these equivalent part numbers.
