1N4371E3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4371E3/TR is a commercial-grade silicon Zener diode with a nominal voltage of 2.7 V and a maximum power dissipation of 500 mW. It features a standard ±5% tolerance, a maximum reverse leakage current of 60 µA at 1.0 V, and a dynamic impedance of 30 Ohms at a test current of 20 mA. The device operates within a temperature range of -65°C to +175°C and utilizes an axial-lead glass DO-35 package.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-35 package with flexible axial leads for through-hole mounting
• Internal metallurgical bond construction for enhanced reliability
• RoHS compliant commercial grade version available
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020

Single Zener Diodes Applications

• Voltage regulation over broad temperature and current ranges
• Reference voltage generation in precision circuits
• Overvoltage protection applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature guide to confirm RoHS compliance status and packaging format. The 'TR' suffix indicates tape and reel packaging per EIA-296 standards. Ensure the selected variant matches the required lead plating specifications for your assembly process.

Single Zener Diodes Selection Notes

Select this component when a 2.7 V reference is required in a standard axial-lead package. Consider the thermal derating curves for ambient temperatures above 55°C or lead temperatures above 50°C. Verify that the 30 Ohm dynamic impedance meets the ripple rejection requirements of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N4370A through 1N4372A series of 500 mW Zener voltage regulators. The series offers a selection from 2.4 to 12 volts with standard 5% tolerances. While military qualified levels exist for this series, the e3 suffix denotes a commercial grade RoHS compliant version.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering JEDEC registered 1N4371 equivalents in DO-35 packages. Ensure replacement parts match the 2.7 V nominal voltage, 500 mW power rating, and ±5% tolerance specifications.
