Single Zener Diodes Procurement Notes

Verify the complete part number including the suffix /TR to confirm reel packaging. Ensure the DO-213AA footprint matches the design layout. Confirm RoHS compliance status if required by specific project standards. Cross-reference the manufacturer's latest datasheet for any potential pinout or parameter updates before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 11 V regulation point is required in a space-constrained surface-mount design. The 500 mW rating supports moderate current loads. Consider the 30 Ohm impedance for noise-sensitive applications. Verify that the operating current stays within the specified test conditions to maintain accuracy.

Single Zener Diodes Part Context

This component belongs to the 1N52xxB series of Zener diodes from Microchip Technology. These devices are silicon planar junction rectifiers optimized for voltage regulation. The BUR-1 designation typically indicates specific manufacturing lot or revision details, while /TR denotes tape and reel packaging for automated assembly.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 11 V Zener diodes in SOD-80 packages with similar 500 mW ratings. Verify compatibility regarding Zener impedance and leakage current specifications. Ensure thermal management requirements align with the replacement device's power dissipation capabilities.
