1N5275BUR/TR

Single Zener Diodes Overview

The 1N5275BUR/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tolerance of 5%. The device operates in the DO-213AA-2 (SMA) surface-mount package and supports through-hole mounting styles. Key electrical parameters include a maximum reverse leakage current of 100 nA and a Zener impedance of 850 Ohms at a test current of 2.5 mA. It dissipates up to 500 mW of power and functions within a temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a 100 V nominal breakdown voltage.
• Offers low leakage current characteristics for efficient circuit operation.
• Supports surface-mount installation via the compact DO-213AA-2 package.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels.
• Over-voltage protection stages in electronic systems.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required packaging formats. Confirm that the DO-213AA-2 footprint matches your PCB design constraints. Cross-reference the thermal dissipation ratings with your system's operating environment to maintain reliability under load conditions.

Single Zener Diodes Selection Notes

Select this component when a 100 V regulation point is required in a surface-mount layout. Ensure the 500 mW power rating aligns with the expected current draw in your application. Consider the 850 Ohm impedance value for noise sensitivity requirements in sensitive analog sections.

Single Zener Diodes Part Context

This part belongs to the Microchip 1N52xx series of Zener diodes, which are widely used for basic voltage clamping and reference duties. The BUR variant indicates a specific tape-and-reel packaging option suitable for automated assembly processes, distinguishing it from bulk or other reel configurations.

Single Zener Diodes Replacement Considerations

Consult official substitution guides for equivalent parts with matching 100 V ratings and compatible SMA packages. Verify pinout compatibility before replacing existing components in established designs.
