Procurement Notes

Verify the specific manufacturer designation as Lumimax Optoelectronic Technology when sourcing this component. Confirm that the ordering suffix 'A' corresponds to the required ±5% tolerance specification. Ensure compatibility with through-hole mounting processes and verify lead plating standards against MIL-STD 750 method 2026 requirements for solderability.

Selection Notes

Select this component for designs requiring a stable 36 V reference point with moderate precision. The DO-41 glass package offers robust thermal performance suitable for high-temperature environments. Consider the 50 Ohm impedance limit when designing for dynamic load variations. Verify that the 1 W power rating aligns with the expected thermal dissipation in the final assembly.

Part Context

This part belongs to the 1N47xxA series of Zener diodes manufactured by Lumimax Optoelectronic Technology. The series covers a wide voltage range from 3.3 V to 75 V, all sharing similar mechanical and electrical characteristics. The 1N4753A specifically targets the 36 V segment of this lineup, utilizing standard axial lead technology for general-purpose electronic applications.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4753A designation, such as onsemi or Vishay, ensuring identical DO-41 packaging and ±5% tolerance. Verify that substitute parts meet the same 1 W power dissipation and 200°C junction temperature ratings.
