Single Zener Diodes Procurement Notes

Verify the specific package variant (DO-7 or DO-35) required for your design, as availability may vary by manufacturer suffix. Confirm RoHS compliance status directly with the supplier, as historical data indicates some variants may not meet current environmental standards. Ensure the selected component matches the exact voltage tolerance and power dissipation requirements of your circuit design before procurement.

Single Zener Diodes Selection Notes

Select this component when a 56 V reference is needed with moderate precision. Consider the 500 mW power rating against expected circuit loads. Verify that the axial leaded package fits the board layout constraints. Compare the 150 Ohm impedance against dynamic load requirements to ensure adequate regulation performance under varying current conditions.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of Zener diodes, widely used for general-purpose voltage regulation. The 'B' suffix typically denotes a tighter voltage tolerance compared to non-suffixed versions. Microchip Technology continues to support legacy parts through various manufacturing sites, ensuring long-term availability for industrial and automotive designs.

Single Zener Diodes Replacement Considerations

The 1N5263BUR-1 serves as a surface-mount equivalent in the DO-213AA package. Direct pin-to-pin replacements from other manufacturers must match the 56 V nominal voltage, 500 mW power rating, and compatible package dimensions.
