1N5271BE3/TR

Single Zener Diodes Overview

The Microchip Technology 1N5271BE3/TR is a single silicon Zener diode housed in a DO-204AH (DO-35) through-hole package. It features a nominal Zener voltage of 100 V with a 5% tolerance and a maximum power dissipation of 500 mW. The device operates within a temperature range of -65 °C to +175 °C, has a test current of 1.3 mA, and exhibits a maximum reverse leakage current of 100 nA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Utilizes hermetically sealed glass encapsulation for environmental protection
• Designed for high-temperature operation up to 175 °C

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the manufacturer designation on the component marking, as this part number is associated with multiple vendors including Microsemi and Microchip. Confirm the specific datasheet version matches your design requirements. Ensure the DO-35 package dimensions align with your PCB footprint. Check for RoHS compliance status if required by your assembly process.

Single Zener Diodes Selection Notes

Select this component when a 100 V regulation point is needed in a standard axial leaded package. Consider the 500 mW power rating against expected operating currents. Evaluate the -65 °C to +175 °C temperature range against your environmental conditions. Compare the 500 Ohm impedance against circuit sensitivity requirements.

Single Zener Diodes Part Context

This component belongs to the 1N5271 series of Zener diodes. It shares the same electrical specifications as the 1N5271B but includes the E3 suffix indicating lead-free composition. The DO-204AH package is a standard industry form factor for general-purpose discrete diodes.

Single Zener Diodes Replacement Considerations

The 1N5271B is a direct functional equivalent from onsemi. The 1N5271DE3 offers similar performance with 1% tolerance from Microsemi. Verify pinout compatibility and thermal characteristics before substitution.
