1N4571-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4571-1/TR is a temperature-compensated Zener diode with a nominal voltage of 6.4 V and a tight tolerance of ±0.1%. It operates at a test current of 0.5 mA and dissipates up to 500 mW in a DO-35 axial package. The device features a low voltage temperature coefficient of 0.001%/°C, ensuring high stability across the -55°C to +100°C operating range.

Single Zener Diodes Feature Summary

• Temperature compensated design for enhanced voltage stability
• High precision voltage tolerance of ±0.1%
• Low voltage temperature coefficient of 0.001%/°C

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature compensated oscillator circuits
• High-stability power supply regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' indicates the ±0.1% tolerance variant distinct from standard versions. Confirm the '/TR' designation corresponds to tape-and-reel packaging requirements. Ensure the manufacturer part number matches the exact specification sheet for the 1N4571A series to validate the 0.5 mA test current rating.

Single Zener Diodes Selection Notes

Select this component when circuit stability requires minimal drift over wide temperature variations. The ±0.1% tolerance makes it suitable for applications where standard Zener tolerances are insufficient. Verify that the 500 mW power dissipation aligns with the thermal management capabilities of the target PCB layout.

Single Zener Diodes Part Context

This component belongs to the Microchip 1N4571A family of temperature-compensated Zener diodes. These devices utilize specific doping profiles to achieve near-zero temperature coefficients around the 6.4 V breakdown region, distinguishing them from standard Zener diodes which exhibit higher thermal drift.

Single Zener Diodes Replacement Considerations

Substitutes must match the 6.4 V nominal voltage, ±0.1% tolerance, and DO-35 package. Verify that alternative manufacturers provide equivalent temperature coefficient specifications to maintain circuit performance.
