Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the official Microchip datasheet to ensure compliance with required tolerance and environmental standards. Confirm that the DO-213AA package dimensions align with the target PCB footprint. Validate that the component meets all necessary radiation hardness or qualification requirements for the intended operational environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with high voltage accuracy is required. The ±1% tolerance distinguishes it from standard commercial variants. Ensure the design accommodates the 500 mW power rating and the thermal constraints of the DO-213AA package. Consider the extended temperature range if the application involves extreme environmental conditions.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes, which are typically characterized for enhanced reliability compared to commercial grades. The 'TX' designation indicates a specific quality level within the Microchip portfolio. It serves as the surface-mount equivalent to the through-hole 1N5528B family, maintaining similar electrical characteristics while adapting to modern SMT manufacturing processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JAN-series Zener diodes with identical 8.2 V ratings and DO-213AA packaging, such as the JAN1N5528DUR-1/TR. Verify that any replacement matches the ±1% tolerance and high-temperature specifications to maintain circuit integrity.
