1N4571A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4571A-1/TR is a temperature-compensated Zener diode with a nominal voltage of 6.4 V and a tolerance of ±0.5%. It operates within a wide temperature range from -65°C to +175°C, featuring a maximum reverse leakage current of 2 µA and a Zener impedance of 100 Ohms at a test current of 1 mA. The device dissipates up to 500 mW in a DO-204AH (DO-35) axial through-hole package. This reel-packaged component provides high stability for precision applications requiring minimal thermal drift.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm lead-free status and packaging format. Ensure the procurement order matches the exact part number designation to avoid discrepancies in tolerance or temperature coefficient specifications. Cross-reference manufacturer documentation for any recent product change notices affecting this variant.

Single Zener Diodes Selection Notes

Select this component when strict voltage stability over temperature is required. The narrow ±0.5% tolerance distinguishes it from standard Zener diodes. Verify that the 500 mW power dissipation rating aligns with the circuit's thermal management capabilities. Confirm compatibility with through-hole assembly processes given the DO-204AH package style.

Single Zener Diodes Part Context

This part belongs to the 1N4571 series of temperature-compensated Zener diodes manufactured by Microchip Technology. It shares the fundamental 6.4 V characteristic with other variants but offers tighter tolerance and superior thermal performance compared to standard models like the 1N4571A. The series is designed for applications demanding high reliability and precise voltage references.
