1N5272A-1

Single Zener Diodes Overview

The Microchip Technology 1N5272A-1 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 110 V with a tolerance of ±10%. The device has a maximum power dissipation of 500 mW and operates in the through-hole DO-204AH (DO-35) axial package. It is unidirectional, hermetically sealed in glass, and contains two pins.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 110 V with high precision tolerance
• Constructed with hermetically sealed glass encapsulation for durability
• Designed for through-hole mounting in standard axial configurations

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 110 V levels
• Overvoltage protection in electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix -1 indicates the standard axial variant distinct from other packaging options. Confirm RoHS compliance status as some variants may differ. Ensure the supplier provides official Microchip documentation to validate the part number authenticity and manufacturing origin before purchase.

Single Zener Diodes Selection Notes

Select this component when a fixed 110 V regulation point is required within a 500 mW power budget. The DO-35 package suits space-constrained through-hole designs. Consider the ±10% tolerance if tighter regulation is needed, or evaluate higher power variants for thermal management requirements in dense assemblies.

Single Zener Diodes Part Context

This part belongs to the 1N527x series of single Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings in the same axial glass package family. The 1N5272A-1 specifically targets the 110 V segment, providing a reliable solution for legacy and modern mixed-signal circuit designs requiring discrete voltage regulation.

Single Zener Diodes Replacement Considerations

Direct substitutes include the non-suffixed 1N5272A which shares identical electrical characteristics and pinout. Verify package compatibility when replacing with generic equivalents to ensure the DO-35 form factor matches the existing PCB footprint.
