1N5275/TR

Single Zener Diodes Overview

The Microchip Technology 1N5275/TR is a Zener diode designed for voltage regulation applications. It operates within the DO-35 axial leaded package, providing a nominal Zener voltage of 100V with a power dissipation rating of 500mW. The component features a tight voltage tolerance of 1% and maintains a maximum reverse leakage current of 100nA at the specified test conditions. It supports through-hole mounting and functions reliably across an extended temperature range from -65°C to +200°C junction temperature.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with 1% tolerance for high-stability circuits
• Utilizes glass axial-leaded DO-35 package for robust through-hole integration
• Supports high-temperature operation up to 200°C junction temperature

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection systems
• High-temperature industrial control electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration when sourcing. Confirm the 1% tolerance variant matches design requirements against standard 5% or 10% versions. Ensure the manufacturer documentation aligns with the requested part number to avoid confusion with similar series components lacking the tight tolerance specification.

Single Zener Diodes Selection Notes

Select this component when circuit stability requires tighter voltage tolerances than standard Zener diodes provide. The 500mW power rating suits low-to-moderate current regulation tasks. Verify that the DO-35 package dimensions fit the PCB layout constraints and that the operating environment remains within the specified thermal limits for reliable long-term performance.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5-watt Zener Voltage Regulators manufactured by Microchip Technology. The series offers a wide selection of voltages from 2.4 to 200 volts in standard packages. The 1N5275 represents the 100V option within this lineup, distinguished by its enhanced 1% tolerance classification compared to general-purpose variants.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 100V 500mW Zener diodes with 1% tolerance in DO-35 packages. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with Microchip's official replacement guide for exact electrical matching.
