JANTXV1N4566A-1

Single Zener Diodes Overview

The JANTXV1N4566A-1 is a silicon Zener reference diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.4 V with a tolerance of ±5%. The device operates in the DO-35 (DO-204AH) axial leaded package and supports through-hole mounting. Key electrical parameters include a maximum power dissipation of 0.5 W, a reverse leakage current of 2 µA at 3 V, and a Zener impedance of 200 Ohms. It is qualified to MIL-PRF-19500/452 standards and offers an internal metallurgical bond construction.

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application, as the -1 suffix denotes internal metallurgical bonding which may affect availability or lead times compared to standard versions. Confirm that the DO-35 package dimensions align with your PCB layout constraints. Ensure that the MIL-PRF-19500/452 qualification meets your program's quality assurance standards before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is required in a through-hole axial package. The JANTXV prefix indicates a high-reliability military grade device. Consider the 200 Ohm Zener impedance if low dynamic resistance is not critical. Compare against other voltages in the 1N4565-1N4584A series if different reference levels are needed.

Single Zener Diodes Part Context

This part belongs to the popular 1N4565 through 1N4584A series of Zero-Temperature Coefficient Reference Diodes. These devices are designed to provide minimal voltage change over temperature variations. The series includes various nominal voltages, with the 6.4 V variant being a common choice for temperature compensation due to its near-zero TC characteristics.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTX1N4566A-1 and JAN1N4566A-1, which share the same electrical specifications but differ in military qualification levels. Surface mount equivalents are available in the DO-213AA package, such as the JANTXV1N4566AUR-1, for applications requiring SMT technology.
