• Power supply protection against overvoltage conditions
• Reference voltage generation in electronic systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'e3' indicates RoHS compliance, and '/TR8' denotes tape and reel packaging. Confirm the manufacturer origin as Microsemi (now part of Microchip Technology) Scottsdale Division. Ensure the component meets the specified JEDEC registration standards for the 1N5344B series. Cross-reference the datasheet revision D for accurate electrical parameters before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt axial-leaded Zener diode with an 8.2V nominal voltage and ±5% tolerance is required. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Evaluate the maximum surge current capability for transient protection needs. Ensure the operating environment stays within the -65°C to +150°C temperature range and that the package dimensions fit the PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options indicated by suffix letters. These devices are designed for applications requiring robust voltage regulation and high power handling capabilities in a plastic encapsulated axial-lead package.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5344B or SMBG5344B are available from the same manufacturer. Verify pin compatibility and thermal performance when substituting axial leads with surface mount packages. Ensure the replacement part maintains the same voltage rating and tolerance specifications.
