Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure correct voltage and tolerance specifications. Check RoHS compliance status if required for your assembly process. Ensure the ordering quantity aligns with the standard reel pack size provided by the supplier. Validate the component authenticity through authorized distribution channels.

Single Zener Diodes Selection Notes

Select this component when a 16 V regulated potential is required in through-hole designs. Consider the 500 mW power dissipation limit for thermal management calculations. The axial leaded package facilitates easy insertion into standard PCB layouts. Verify that the 13 Ohm impedance meets the dynamic regulation requirements of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of glass-passivated Zener diodes produced by Microchip Technology. The series covers a wide range of voltage values for various regulation needs. The /TR suffix typically denotes tape and reel packaging for automated assembly processes. These diodes are widely used in industrial and commercial electronics for reliable voltage control.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 16 V Zener voltage, 500 mW power rating, and DO-204AH-2 package. Verify equivalent impedance and leakage current specifications to maintain circuit performance. Cross-reference with other manufacturers' 1N5247 equivalents ensuring identical electrical characteristics.
