Single Zener Diodes Procurement Notes

Verify that the specific suffix '-1/TR' aligns with the required packaging format, as datasheets may list bulk or reel options. Confirm compliance with MIL-PRF-19500/115 standards if military-grade qualification is necessary. Ensure the DO-204AL package dimensions match the target footprint. Cross-reference the manufacturer's latest PCN documents for any assembly site or labeling changes that may affect part identification.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V regulation point is required with high-temperature capability up to 175°C. The 1 W power rating supports moderate current loads compared to lower-power variants. Consider the axial leaded package for manual assembly or high-vibration environments where surface-mount alternatives might be less secure. Verify that the 7 Ohm impedance meets the dynamic regulation requirements of the specific circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N3821A through 1N3828A family of 1-watt Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings from 3.3 V to 75 V, all sharing similar physical construction and thermal characteristics. These diodes are commonly specified in industrial and aerospace applications due to their wide operating temperature range and ruggedized double-plug construction.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N3826 equivalents meeting the same electrical specifications. For military specifications, verify compatibility with JAN1N3826A-1 variants. Ensure replacement parts maintain the DO-204AL package and 1 W power dissipation rating to fit existing board layouts and thermal management designs.
