1N5275

Single Zener Diodes Overview

The Microchip Technology 1N5275 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 140V with a standard tolerance of 10%. The device is rated for a power dissipation of 0.5W and operates within a temperature range from -65°C to +175°C. It utilizes a DO-35 glass axial-lead package, providing an isolated configuration suitable for through-hole mounting.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at high potential levels using silicon junction technology.
• Constructed in a hermetically sealed glass axial-lead package for environmental protection.
• Capable of operation in extreme thermal environments up to 175°C.

Single Zener Diodes Applications

• High-voltage reference circuits
• Overvoltage protection stages
• Voltage clamping in industrial control systems

Single Zener Diodes Procurement Notes

Verify the specific suffix letter (e.g., A, B) required for your design, as these indicate distinct voltage tolerances such as 5% or 10%. Confirm whether military screening levels or lead-free compliance are necessary for your project specifications before ordering.

Single Zener Diodes Selection Notes

Select this component when a precise 140V regulation point is needed in a compact axial package. Ensure the circuit current limits allow for safe dissipation of 0.5W. Consider tighter tolerance variants if the application demands stricter voltage accuracy than the standard 10% specification provides.

Single Zener Diodes Part Context

This part belongs to the widely used 1N5221 through 1N5281B series of 0.5-watt Zener diodes. The series offers a broad selection of voltages from 2.4V to 200V in standard packages. The 1N5275 specifically addresses the high-voltage segment of this legacy lineup, maintaining compatibility with traditional through-hole PCB layouts.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5275 equivalents. Verify that substitute parts match the 140V Zener voltage, 0.5W power rating, and DO-35 package dimensions to ensure mechanical and electrical interchangeability.
