Single Zener Diodes Procurement Notes

Verify that the ordering code includes the suffix 'T' to confirm the specific taped packaging format. Ensure the required voltage tolerance aligns with the standard 'B' designation specifications. Confirm compliance requirements against the material categorization definitions provided in the official documentation before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when an axial leaded package is required for through-hole mounting. The 13 V nominal rating suits applications needing precise low-voltage regulation. Consider the 500 mW power dissipation limit and thermal resistance constraints during circuit design to ensure reliable operation under expected load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 2.4 V to 75 V. The 1N5243B variant specifically addresses the 13 V segment within this extensive lineup of standard tolerance devices.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes rated at 13 V with similar power dissipation capabilities. Verify that alternative parts meet the same electrical parameters, including dynamic resistance and leakage current limits, to ensure functional compatibility.
