Single Zener Diodes Procurement Notes

Verify the manufacturer marking and date code on the physical component against official Microsemi documentation. Confirm the package type matches the specified DO-41 axial lead configuration. Ensure the part number suffix 'AG' corresponds to the correct tolerance and testing standards defined in the datasheet before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 5.6 V reference is required in through-hole designs. Consider the power dissipation limits and thermal resistance of the DO-41 package during circuit design. Evaluate the Zener impedance and leakage current specifications against the precision requirements of the target application to ensure adequate performance margins.

Single Zener Diodes Part Context

This component belongs to the 1N47 series of Zener diodes manufactured by Microsemi Corporation. The series offers various voltage options within a standardized axial leaded package format. These devices are commonly used in general-purpose electronics where reliable voltage clamping or referencing is necessary without requiring complex active regulation components.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4730 equivalents such as ON Semiconductor or Vishay.
