Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact electrical tolerances and testing levels. Ensure the procurement channel sources genuine components with traceable manufacturing records. Confirm RoHS compliance status as required by project specifications, noting that some legacy variants may not meet current environmental directives.

Selection Notes

Select this component when a stable 82 V reference is required at high power levels. The TO-204AD package necessitates adequate heatsinking infrastructure on the PCB or chassis. Verify that the system's thermal design can dissipate up to 50 W while maintaining junction temperatures within the specified -65°C to +175°C operational window for reliable long-term performance.

Part Context

This part belongs to the standard 1N28xx series of high-power Zener diodes manufactured by Microchip Technology. These devices are widely utilized in legacy and ruggedized electronics where silicon stability and high wattage ratings are critical. The TO-3 metal case construction offers superior thermal conductivity compared to plastic packages, making it ideal for high-current shunt regulation applications.

Replacement Considerations

Cross-reference with other manufacturers' 1N2836A equivalents such as those from Microsemi or Central Semiconductor. Verify pinout compatibility and ensure the replacement meets the same 50 W power rating and 82 V Zener voltage specifications.
