1N4570A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4570A-1/TR is a temperature-compensated Zener diode with a nominal voltage of 6.4 V and a tolerance of +/-1%. It operates in the DO-204AH-2 (DO-35) through-hole package, dissipating up to 500 mW. Key electrical parameters include a test current of 0.5 mA, maximum reverse leakage current of 2 uA, and Zener impedance of 100 Ohms. The device functions within a temperature range of -65 C to +175 C, featuring a voltage temperature coefficient of 0.01 %/C.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable voltage regulation across wide thermal ranges
• Hermetically sealed glass construction ensuring environmental durability

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature compensation networks
• Overvoltage protection in harsh environments

Single Zener Diodes Procurement Notes

Verify the specific suffix -1/TR confirms reel packaging when ordering. Confirm RoHS status as non-compliant based on available documentation. Ensure the DO-35 package dimensions match the target PCB layout requirements before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when high stability over temperature is required compared to standard Zener diodes. The 6.4 V rating suits mid-range reference needs. Consider the hermetic seal for reliability in aerospace or industrial settings where standard plastic packages may fail.

Single Zener Diodes Part Context

This part belongs to the military-grade or high-reliability Zener diode family from Microchip. It shares characteristics with other 1N45xx series devices but offers tighter voltage tolerance and temperature compensation features distinct from commercial grade equivalents.

Single Zener Diodes Replacement Considerations

Check for direct substitutes like 1N4570A without the reel suffix if bulk packaging is acceptable. Verify equivalent temperature coefficients and leakage currents when considering alternative manufacturers.
