• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify that the part number includes the e3 suffix to confirm RoHS compliance and the TR8 suffix to ensure tape and reel packaging. Confirm the B suffix indicates the standard ±5% voltage tolerance. Ensure the supplier provides documentation matching the Microsemi datasheet specifications for thermal resistance and maximum ratings.

Single Zener Diodes Selection Notes

Select this component when a 4.3V Zener reference is required with 5-watt power handling capabilities. Consider the axial lead format for through-hole mounting or specific heat sinking requirements. Evaluate the thermal resistance characteristics against the expected ambient temperature and current load to ensure operation within the specified junction-to-lead limits.

Single Zener Diodes Part Context

This component belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These devices are designed for applications requiring robust voltage regulation and high current handling under adequate heat sinking conditions.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5336B or SMBG5336B are available from the same manufacturer. Verify pinout compatibility and thermal management requirements when substituting axial leads with surface mount packages.
