Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as this part number originates from Microsemi which was acquired by Microchip Technology. Confirm RoHS compliance status and check for any discontinuance notifications or lifecycle changes associated with the legacy Microsemi product line before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and an 8.2-volt regulation point are required. Ensure the design accommodates the thermal resistance characteristics and provides sufficient heat sinking to maintain operation within the specified maximum junction temperature limits during steady-state conditions.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by suffix letters such as B for ±5%.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5-watt axial Zener diodes with 8.2V regulation and ±5% tolerance. Verify mechanical dimensions and thermal performance match the T-18 package specifications.
