• ESD protection applications

Single Zener Diodes Procurement Notes

Verify the specific suffix letters on the part number to confirm voltage tolerance and RoHS compliance status. Ensure the ordering suffix matches the required reliability level and packaging option. Confirm that the metallurgically bonded construction meets the environmental requirements for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a surface mount equivalent to the JEDEC registered 1N5221 series is required. Choose this part for applications needing a 62 V breakdown voltage with tight tolerance. Consider the low capacitance and radiation hardness for specialized environments.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series of 0.5 watt Zener voltage regulators. The series offers a surface mount alternative to traditional axial-leaded components, covering a voltage range from 2.4 to 200 volts in a compact glass package.

Single Zener Diodes Replacement Considerations

The 1N5265BDO35 serves as a parameter-equivalent axial-leaded replacement within the same product family.
