1N4371A/TR

Overview

The 1N4371A/TR is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 2.7 V with a 5% tolerance and operates at a test current of 20 mA. The device has a maximum power dissipation of 500 mW and a Zener impedance of 30 Ohms. It supports a reverse current of up to 140 mA and exhibits a forward voltage of 1.1 V at 200 mA. The component is housed in a DO-204AH (DO-35) axial through-hole package and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation with a nominal 2.7 V output.
• Features low Zener impedance for effective noise filtering.
• Supports high thermal stability across an extended temperature range.

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the DO-35 package dimensions match the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring a precise 2.7 V reference point. Consider the 500 mW power rating for thermal management in enclosed spaces. Verify that the 30 Ohm impedance meets the ripple rejection requirements of the specific circuit application.

Part Context

This part belongs to the standard 1N437x series of Zener diodes produced by Microchip Technology. It shares the same DO-35 axial leaded form factor as other variants in the family, allowing for interchangeable mounting in legacy through-hole designs requiring similar voltage regulation characteristics.
