Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package specification as defined by onsemi. Confirm the specific package type matches the required mechanical constraints, noting that this component uses the Case 017AA axial lead configuration. Ensure compliance with RoHS directives if lead-free materials are mandatory for the assembly process.

Single Zener Diodes Selection Notes

Select this component when a precise 30 V reference with tight tolerance is required. The 5 W power rating allows for significant current handling compared to lower-power alternatives. Consider the thermal resistance characteristics and derating requirements above 25°C ambient temperature to ensure reliable operation under continuous load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series, a comprehensive line of 5 Watt Zener diodes ranging from 3.3 V to 200 V. The series is characterized by tight limits and improved reliability due to the silicon-oxide passivation technology. It serves as a standard solution for medium-power voltage regulation tasks in industrial and commercial electronics.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5363BRL from NXP and the 1N5363BE3 from Microsemi. These parts share the same nominal 30 V Zener voltage and 5 W power dissipation rating. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit.
