Single Zener Diodes Procurement Notes

Verify the specific suffix Be3 against procurement requirements, as it indicates lead-free status and tape-and-reel packaging. Confirm that the DO-35-2 through-hole package aligns with board layout constraints. Ensure the 500 mW power rating is sufficient for the intended thermal environment. Check compatibility with automated assembly processes due to reel packaging.

Single Zener Diodes Selection Notes

Select this component when a precise 110 V reference is required in a compact axial leaded format. The 5% tolerance suits general regulation tasks where tight precision is not critical. Consider the 750 Ohm impedance for noise-sensitive designs. Evaluate the -65 C to +175 C range against environmental conditions. Compare with other 1N52xx series variants if different voltage levels are needed.

Single Zener Diodes Part Context

This part belongs to the standard 1N527x series of Zener diodes manufactured by Microchip Technology. These components are widely used in discrete semiconductor applications requiring reliable voltage clamping. The DO-35 package is a common industry standard for small-signal diodes. The series offers various voltage options within a consistent physical footprint.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5272 equivalents. Verify pinout compatibility and package dimensions for direct substitution. Ensure Zener voltage and power dissipation ratings meet or exceed original specifications.
