1N4570A

Single Zener Diodes Overview

The Microchip Technology 1N4570A is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a tolerance of ±5%. It operates in the DO-204AH (DO-35) through-hole package, dissipating up to 500 mW. The device features a low voltage temperature coefficient of 0.01%/°C and a maximum reverse leakage current of 2 µA at 3 V. It functions within an extended temperature range from -65°C to +175°C, with a test current of 500 µA and a Zener impedance of 100 Ohms.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as this component has been produced by multiple entities including Microsemi and Microchip Technology. Confirm that the DO-204AH package matches your board layout requirements. Ensure the ±5% tolerance aligns with your circuit's precision needs. Check for RoHS compliance status if environmental regulations apply to your assembly process.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is required in a standard axial leaded package. The low temperature coefficient makes it superior to standard Zener diodes for wide thermal environments. Consider the 500 mW power dissipation limit for thermal management. Verify compatibility with existing MIL-PRF-19500/452 qualified variants if military standards are mandatory.

Single Zener Diodes Part Context

This part belongs to the popular 1N4565 through 1N4584A series of Zero-TC Reference Diodes. These devices provide a selection of nominal voltages centered around 6.4 V with extremely low temperature coefficients. The series is widely recognized for its reliability in high-performance analog applications requiring precise voltage regulation over varying thermal conditions.

Single Zener Diodes Replacement Considerations

JAN1N4570AUR-1 serves as a surface mount equivalent in the DO-213AA package. For hermetic glass axial versions, the 1N4570A-1 suffix indicates metallurgical bonding. Other series members like 1N4568A-1 offer tighter tolerances but may differ in temperature coefficients.
