Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm electrical tolerances and screening levels. Ensure the ordering code matches the required RoHS compliance status indicated by the e3 designation. Confirm that the tape and reel packaging aligns with automated assembly requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 130 V regulation point is required within a standard axial-lead form factor. Consider the thermal derating curves for high ambient temperatures to maintain the 500 mW power limit. Evaluate the Zener impedance value to ensure it meets the dynamic load requirements of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microsemi, now part of Microchip Technology. The series offers a wide selection of voltages from 2.4 V to 200 V in the DO-35 package. The B suffix denotes a standard 5% voltage tolerance.

Single Zener Diodes Replacement Considerations

Direct pin-for-pin replacements include other manufacturers' 1N5274 variants meeting JEDEC specifications. Verify that substitute parts match the 130 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility.
