1N4570-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4570-1/TR is a temperature-compensated Zener diode housed in the DO-204AH (DO-35) axial through-hole package. It features a nominal Zener voltage of 6.4 V with a tight tolerance of ±1%. The device dissipates up to 500 mW and operates within an extended temperature range of -65°C to +175°C. Key electrical characteristics include a maximum Zener impedance of 50 Ohms and a reverse leakage current of 2 µA at 3 V.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable voltage regulation across wide thermal ranges
• High precision ±1% voltage tolerance for sensitive reference applications
• Extended operating temperature capability suitable for harsh environments

Single Zener Diodes Applications

• Regulated power supply output stabilization

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required tolerance and packaging standards. Confirm RoHS compliance status as it varies by manufacturing lot and region. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Single Zener Diodes Selection Notes

Select this component when high stability and precise voltage regulation are critical under varying thermal conditions. The ±1% tolerance distinguishes it from standard variants, making it suitable for precision instrumentation. Ensure the through-hole DO-35 package aligns with the target PCB layout constraints and assembly processes.

Single Zener Diodes Part Context

This part belongs to the 1N4565–1N4584A series of temperature-compensated Zener diodes manufactured by Microchip Technology. These devices utilize a specific junction structure to minimize voltage drift over temperature, offering superior performance compared to standard Zener diodes in precision analog applications.

Single Zener Diodes Replacement Considerations

The 1N4570A serves as a parameter-equivalent alternative but typically carries a ±5% tolerance rather than the ±1% specified for the -1 variant. Verify that the reduced precision of the substitute meets the circuit requirements before substitution.
