Procurement Notes

Verify the specific qualification level required, as this component family includes JAN, JANTX, and JANTXV variants. Confirm that the ordering suffix matches the desired reliability standard. Ensure the package type aligns with thermal management requirements. Check for any recent product change notifications affecting specifications or manufacturing locations before finalizing procurement.

Selection Notes

Select this component when a 50 Watt Zener diode with an 8.2 V nominal voltage is required. Ensure the application can accommodate the TO-204AD through-hole package and associated thermal dissipation needs. Verify that the ±10% tolerance meets the circuit's precision requirements. Consider the operating temperature range to ensure compatibility with the environmental conditions of the target system.

Part Context

This part belongs to the 1N2804B through 1N2846B series of 50 Watt Zener diodes registered with JEDEC. These components are designed for rugged environments and are qualified per MIL-PRF-19500/114 standards. The series covers a wide voltage range from 3.9 V to 200 V, offering versatile solutions for high-power regulation tasks in demanding applications.

Replacement Considerations
