Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR12 corresponds to the tape and reel packaging option specified in the datasheet. Confirm RoHS compliance status by checking for the e3 designation on the specific part marking or documentation. Ensure the supplier provides valid traceability data for the Microsemi Scottsdale Division manufacturing origin.

Single Zener Diodes Selection Notes

Select this component when a 28 V reference with ±5% tolerance is required. The 5-watt power rating supports high-current applications provided adequate heat sinking is implemented. Verify thermal resistance requirements against the derating curves for the specific mounting environment. Consider the T-18 package dimensions for PCB layout constraints.

Single Zener Diodes Part Context

This device is part of the Microsemi 1N5333B through 1N5388B series of silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The B suffix indicates a standard voltage tolerance of plus or minus 5%. The series is JEDEC registered and designed for robust performance in industrial and commercial applications.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMBJ5362B or SMBG5362B. Other manufacturers may offer direct replacements within the 1N53xx series, but electrical parameters and package dimensions must be verified against the original specifications.
