1N4730A_S00Z

Overview

The onsemi 1N4730A_S00Z is a silicon planar Zener diode designed for voltage regulation and clipping applications. It features a nominal Zener voltage of 3.9 V with a 5% tolerance, tested at a current of 64 mA. The device operates within the DO-41 glass axial lead package and supports a maximum steady-state power dissipation of 1.0 W at lead temperatures up to 50°C. It withstands operating and storage temperatures ranging from -65°C to +200°C.

Feature Summary

• Utilizes silicon planar technology for robust voltage regulation performance
• Features a hermetically sealed glass DO-41 package for environmental protection
• Includes oxide passivated die construction for enhanced reliability

Applications

• Voltage regulation circuits
• Signal clipping applications
• Reference voltage generation

Procurement Notes

Verify that the specific ordering suffix matches the required packaging configuration. Confirm compliance with RoHS directives if applicable to the manufacturing batch. Ensure the component meets the necessary military or industrial screening standards required by the final system design specifications before integration.

Selection Notes

Select this component when a precise 3.9 V reference is needed in an axial lead format. Consider the thermal derating requirements above 50°C to maintain the 1.0 W rating. Evaluate the dynamic impedance characteristics against the circuit's noise sensitivity requirements.

Part Context

This part belongs to the standard 1N47xx series of one-watt Zener diodes licensed by ON Semiconductor. The series covers a wide voltage range from 3.3 V to 100 V. The 'A' suffix typically denotes a tighter 5% voltage tolerance compared to standard variants.

Replacement Considerations

Equivalent parts include the 1N4730A from other manufacturers such as Microsemi or Vishay. Surface mount equivalents like the SMAJ4730A are available for high-density designs requiring JEDEC outline compatibility.
