Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as historical production involves Microsemi and current branding may reflect Microchip Technology acquisitions. Confirm RoHS compliance status, as some listings indicate non-compliance. Ensure the TO-204AD package matches your PCB footprint requirements. Check for any specific ordering suffixes that might affect electrical parameters or packaging format before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference with significant power dissipation capacity is required. The TO-3 package necessitates adequate heatsinking and mechanical mounting provisions. Consider the ±10% tolerance if tighter precision is needed, in which case lower-tolerance variants within the family should be evaluated. Ensure the application voltage does not exceed the maximum ratings defined in the official datasheet.

Single Zener Diodes Part Context

This part belongs to the 1N4562 series of 50-watt Zener diodes. Variants such as 1N4562B offer different voltage ratings within the same power class. The series is characterized by its ability to maintain regulation under high current loads, making it distinct from lower-power signal Zener diodes. Historical documentation links this part to both Motorola and Microsemi manufacturing origins.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 50W Zener diodes with a 6.2V rating in TO-3 packages. Verify pinout compatibility and thermal resistance specifications. Cross-reference with 1N4562B if voltage adjustment is permissible. Ensure replacement parts meet the same power dissipation and tolerance requirements.
