1N5530A

Overview

The Microchip Technology 1N5530A is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 10 V with a tolerance of ±10%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. Electrical characteristics include a reverse leakage current of 50 nA at 8 V and a forward voltage of 1.1 V at 200 mA. It utilizes the DO-204AH (DO-35) axial through-hole package.

Feature Summary

• Provides stable voltage regulation with a nominal 10 V Zener breakdown.
• Capable of handling up to 500 mW of power dissipation.
• Engineered for high-temperature operation up to 175°C junction temperature.
• Constructed in a standard glass axial leaded package for through-hole mounting.

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Procurement Notes

Verify the specific manufacturer source, as Central Semiconductor Corp also lists this part number. Confirm that the component matches the Microchip Technology specification sheet regarding electrical tolerances and thermal ratings. Ensure the package type corresponds to DO-204AH (DO-35). Check for any recent Product Change Notifications affecting assembly sites or labeling before finalizing procurement.

Selection Notes

Select this component when a 10 V regulation point is required with moderate power handling capabilities. The wide operating temperature range makes it suitable for industrial environments. Verify that the ±10% tolerance aligns with circuit requirements. Consider the through-hole form factor if PCB layout constraints favor axial leads over surface-mount alternatives.

Part Context

This component belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options within the same physical package family. The 1N5530A specifically targets the 10 V segment, providing a standardized solution for legacy and modern designs requiring reliable voltage regulation in axial packages.

Replacement Considerations

Publicly confirmed substitute part numbers include 1N5240B from onsemi and Central Semiconductor Corp. These alternatives offer similar electrical characteristics but may differ in packaging or manufacturing origin. Verify compatibility with existing circuit parameters before substitution.
