1N4575-1

Single Zener Diodes Overview

The Microchip Technology 1N4575-1 is a temperature-compensated Zener reference diode featuring a nominal voltage of 6.4 V. It utilizes an internal metallurgical bond construction, indicated by the -1 suffix, to enhance reliability and stability. The device operates at test currents such as 0.5 mA, 1.0 mA, 2.00 mA, or 4.00 mA, providing minimal voltage change over temperature with coefficients as low as 0.0005%/°C. Packaged in DO-35 (DO-204AH), it offers a Zener reference voltage tolerance of ±5% and supports military qualifications.

Single Zener Diodes Procurement Notes

Verify the specific operating current selection required for the application, as the series supports multiple test currents including 0.5 mA, 1.0 mA, 2.00 mA, and 4.00 mA. Confirm if military qualification prefixes such as JAN, JANTX, or JANTXV are necessary for the intended environment. Ensure the DO-35 package form factor aligns with the PCB layout requirements. Cross-reference the datasheet for exact electrical limits under varying thermal conditions.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference with low temperature coefficient is required in an axial-leaded package. The -1 suffix denotes the internal metallurgical bond, which is critical for high-reliability applications. Consider the available operating currents to match the circuit's power dissipation constraints. Evaluate the need for military-grade screening if the application involves harsh environments or strict qualification standards.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microchip Technology. The series provides various nominal voltages centered around 6.4 V with different temperature coefficients. The -1 suffix specifically indicates the internal metallurgical bond option, distinguishing it from standard glass-sealed variants within the same voltage family.

Single Zener Diodes Replacement Considerations

Equivalent surface mount versions are available in the DO-213AA package with the UR-1 suffix, such as JANTX1N4569AUR-1. Other parts in the 1N4565-1N4584A-1 series offer similar functionality but may differ in voltage tolerance or temperature coefficient specifications.
