Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm RoHS compliance status if lead-free requirements are mandatory. Ensure the package type aligns with the intended PCB layout. Check for specific military screening prefixes if high-reliability standards are necessary for the application.

Single Zener Diodes Selection Notes

Select this component when a 62 V Zener voltage with tight 5% tolerance is required. Consider the DO-35 package size for through-hole mounting constraints. Evaluate the thermal resistance and derating curves if operation near maximum power limits is expected. Verify compatibility with existing circuit designs requiring low leakage current.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a broad selection of voltages from 2.4 V to 200 V. Variations in tolerance are available via different suffix letters, such as A for 10%, C for 2%, and D for 1%. Military screening options exist with specific prefixes.

Single Zener Diodes Replacement Considerations

Equivalent parts include MSP1N5265B for hermetic DO-7 packages or MLL5265B for surface mount MELF styles. Cross-reference with other manufacturers offering JEDEC registered 1N5265 types in DO-35 packages. Verify pinout and electrical parameters match before substitution.
