1N4371E3

Single Zener Diodes Overview

The Microchip Technology 1N4371E3 is a silicon Zener diode with a nominal voltage of 2.7 V and a standard tolerance of ±5%. It operates in the DO-35 (DO-204AH) axial-lead glass package, rated for 500 mW power dissipation at +50°C lead temperature. The device features a maximum reverse leakage current of 60 µA and a dynamic impedance of 30 Ohms at a test current of 20 mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed internal metallurgical bond construction
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation over broad temperature ranges
• Reference voltage generation in electronic circuits
• Protection against voltage transients

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance, as this attribute applies strictly to commercial grade versions. Confirm the specific reliability level required, such as JAN, JANTX, or JANTXV, by checking the part nomenclature against the manufacturer's official documentation before procurement.

Single Zener Diodes Selection Notes

Select this component when a 2.7 V reference is needed within the 2.4 to 12 V series. Ensure the application requires the specified ±5% tolerance and can accommodate the 30 Ohm dynamic impedance. Verify that the thermal management strategy aligns with the derating curves provided for both lead-mounted and PCB-mounted configurations.

Single Zener Diodes Part Context

This component belongs to the JEDEC registered 1N746 through 1N759A and 1N4370 through 1N4372A series. These devices are qualified per MIL-PRF-19500/127 for military reliability levels while also offering RoHS compliant commercial grades. The series provides flexible axial-lead mounting terminals suitable for various through-hole applications.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N4371A-1 and 1N4371A/TR variants within the same product family.
