1N5230B-1

Single Zener Diodes Overview

The Microchip Technology 1N5230B-1 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device utilizes a DO-35 (DO-204AH) glass axial leaded package, providing an isolated case connection. Key electrical characteristics include a dynamic impedance of 19 Ω at the test current of 20 mA and a maximum operating temperature of 200 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with tight tolerance limits
• Utilizes hermetically sealed glass axial packaging for environmental protection
• Features high stability and low leakage current characteristics

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N5230B part number is produced by multiple vendors including Microchip, Vishay, and Diodes Incorporated. Confirm that the '1' suffix denotes the specific variant requirements such as hermetic sealing or specific testing standards. Ensure the procurement channel provides valid datasheets matching the requested electrical parameters and package type to avoid substitution errors.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V regulated voltage is required in a through-hole axial configuration. The 500 mW power rating suits low-current regulation tasks. Consider the 19 Ω dynamic impedance for noise sensitivity in the application. Verify compatibility with the DO-35 footprint on the PCB layout. Ensure the operating environment does not exceed the specified thermal limits for long-term reliability.

Single Zener Diodes Part Context

This component belongs to the standard Zener diode family used widely in discrete semiconductor design. It serves as a fundamental passive element for establishing fixed voltage nodes within analog and digital circuits. The DO-35 package is a legacy form factor still prevalent in industrial and automotive electronics where through-hole mounting is preferred for mechanical robustness.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5230B from other manufacturers like Vishay or Diodes Incorporated. Cross-referencing requires verifying identical voltage, tolerance, power dissipation, and package dimensions. Hermetic variants may require specific sourcing if environmental sealing is critical.
