1N4371A

Single Zener Diodes Overview

The Microchip Technology 1N4371A is a silicon Zener diode housed in a glass axial-lead DO-35 package. It provides a nominal Zener voltage of 2.7 V with a tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within an extended temperature range from -65°C to +175°C. Key electrical characteristics include a Zener impedance of 30 Ohms, a reverse leakage current of 60 µA, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a 2.7 V Zener reference.
• Features high thermal stability suitable for extreme environments.
• Utilizes a robust glass axial-lead construction.

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the design specification. Standard versions lack internal metallurgical bonding; add the '-1' suffix if mechanical shock resistance is required. Confirm RoHS compliance by checking for the 'e3' designation. Ensure the selected packaging matches the assembly process needs.

Single Zener Diodes Selection Notes

Select this component when a precise 2.7 V reference is needed in a standard through-hole configuration. Consider the -1 variant for applications requiring enhanced mechanical integrity due to metallurgical bonding. Verify that the 500 mW power rating accommodates the expected operating conditions and ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N4370 series of 0.5 W Zener Voltage Regulators. The series covers voltages from 2.4 V to 12 V. Variants are available with different tolerances and mounting options, including surface mount packages like DO-213AA.

Single Zener Diodes Replacement Considerations

The 1N4371AE3 serves as the lead-free equivalent. For surface mount requirements, the 1N4371AUR-1 offers identical electrical performance in a DO-213AA package.
