Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration. Confirm RoHS compliance status as documentation may vary. Ensure the DO-213AA footprint matches the design layout. Validate that the military grade qualification meets project requirements. Check for any specific handling instructions related to the surface mount package type.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener reference is required in a surface mount format. The DO-213AA package offers space efficiency compared to through-hole alternatives. Consider the 500 mW power rating for thermal management calculations. The wide temperature range makes it suitable for applications exceeding standard commercial limits. Verify the 500 Ohm impedance fits the circuit noise and stability requirements.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology. The JAN designation typically indicates components qualified to military standards, specifically MIL-PRF-19500/117. These devices are engineered for reliability in demanding applications where standard commercial parts may not suffice. The BUR-1 suffix often denotes specific testing or screening levels associated with the manufacturer's military product line.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 100 V Zener voltage, 500 mW power rating, and DO-213AA surface mount package. Verify equivalent electrical parameters such as impedance and leakage current. Ensure the replacement component supports the same -65°C to +175°C operating temperature range. Confirm compatibility with existing PCB footprints and assembly processes.
