JANTXV1N4579A-1/TR

Single Zener Diodes Overview

The JANTXV1N4579A-1/TR is a temperature-compensated Zener reference diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.4 V with a tight tolerance of +/- 0.05% and an extremely low voltage temperature coefficient of 0.0005%/°C. The device operates at a test current of 2 mA, dissipates up to 500 mW, and utilizes a DO-35 glass axial package with an internal metallurgical bond (-1 suffix). It meets MIL-PRF-19500/452G standards for military qualification.

Single Zener Diodes Feature Summary

• Temperature compensated design ensures minimal voltage drift across wide thermal ranges
• Internal metallurgical bond construction enhances mechanical stability and reliability
• Military-grade qualification compliant with MIL-PRF-19500/452G specifications

Single Zener Diodes Applications

• Precision voltage reference sources in high-reliability circuits
• Temperature-compensated oscillator references
• Critical instrumentation requiring stable DC biasing

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the datasheet to confirm the presence of the internal metallurgical bond and exact tolerance class. Ensure the procurement specification explicitly requires the JANTXV military grade level and the -TR tape-and-reel packaging format to match the intended assembly process.

Single Zener Diodes Selection Notes

Select this component when ultra-low temperature coefficients are mandatory for circuit stability. The 6.4 V nominal voltage is optimal for bandgap-like reference applications. Confirm that the 2 mA operating current aligns with the system's power budget and that the DO-35 through-hole package fits the board layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These devices provide a selection of 6.4 V nominal voltages with varying temperature coefficients. The series is widely used in aerospace and defense electronics where long-term stability and radiation hardness are critical requirements.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include JANTXV1N4574A-1 (1 mA test current) or JANTXV1N4570A-1 (1 mA test current). Verify that the alternative part's test current and impedance parameters do not disrupt the existing circuit bias conditions.
