Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as Microsemi's semiconductor division was acquired by Microchip Technology. Confirm that the part number suffix indicates the correct tolerance level and packaging format. Ensure compatibility with existing thermal management designs due to the 3 W power rating. Check for RoHS compliance status if required by project specifications.

Single Zener Diodes Selection Notes

Select this component when a 120 V Zener voltage with tight ±5% tolerance is required. The 3 W power rating allows for higher current operation compared to lower wattage variants. The DO-41 package offers robust mechanical stability for through-hole mounting. Consider thermal derating requirements based on ambient operating conditions.

Single Zener Diodes Part Context

This component belongs to the 3EZ series of axial-leaded Zener diodes produced by Microsemi. The series covers a wide voltage range from 3.6 V to 200 V in a standardized plastic package. These devices are designed for general-purpose voltage regulation and protection tasks in industrial and commercial electronics.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-41 packaged 120 V Zener diodes with 3 W power ratings. Verify electrical parameters such as impedance and leakage current match the original design requirements before substitution.
