Single Zener Diodes Procurement Notes

Verify the specific manufacturer datasheet for the 1N5243/TR part number to confirm exact electrical tolerances and thermal ratings before integration. Ensure that the selected component matches the required Zener voltage and power dissipation specifications for the target circuit design. Cross-reference package dimensions and pin configurations with the PCB layout requirements.

Single Zener Diodes Selection Notes

Select this component when a precise 13 V reference is needed in a through-hole configuration. Consider the 5% voltage tolerance and 500 mW power rating against circuit load requirements. Evaluate the operating temperature range to ensure reliability under expected environmental conditions. Verify compatibility with existing assembly processes for axial leaded components.

Single Zener Diodes Part Context

This component belongs to the standard Zener diode family produced by Microchip Technology. It utilizes the DO-204AH-2 package, commonly known as DO-41, which is widely used in general-purpose electronics. The 'TR' suffix indicates reel packaging for automated assembly processes.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 13 V, 500 mW Zener diodes in the DO-204AH-2 package from manufacturers such as onsemi or Vishay. Ensure equivalent Zener impedance and leakage current specifications are met during substitution.
