JANTXV1N4963US/TR

Single Zener Diodes Overview

The JANTXV1N4963US/TR is a military-qualified Zener voltage regulator manufactured by Microchip Technology. It features a nominal Zener voltage of 16 V with a standard tolerance of 5%. The device is designed for surface-mount installation in the D-5B-2 package, which measures 5.72 mm in length, 3.76 mm in width, and 3.76 mm in height. It supports a maximum power dissipation of 5 W and operates within an extended temperature range from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 3.5 Ohms, and a test current of 75 mA.

Single Zener Diodes Feature Summary

• Military qualification compliant with MIL-PRF-19500/356 standards for high-reliability applications
• Hermetically sealed construction utilizing voidless-glass technology with internal metallurgical bonding
• Extended thermal stability enabling operation across extreme environmental conditions

Single Zener Diodes Applications

• High-reliability aerospace systems requiring fault-tolerant voltage regulation
• Military-grade electronic circuits demanding hermetic sealing
• Harsh environment instrumentation operating at elevated temperatures

Single Zener Diodes Procurement Notes

Verify that the specific suffix US/TR corresponds to the required surface-mount tape-and-reel packaging configuration. Confirm that the military qualification level matches the project's reliability requirements. Ensure the component meets all applicable environmental testing standards mandated by the system design specifications before final integration.

Single Zener Diodes Selection Notes

Select this component when a 16 V reference is required in a compact surface-mount form factor. The 5 W power rating allows for significant current handling capabilities compared to lower-power alternatives. The wide operating temperature range makes it suitable for environments where standard commercial parts would fail due to thermal stress.

Single Zener Diodes Part Context

This part belongs to the industry-recognized 5 Watt Zener Voltage Regulator series produced by Microchip Technology. The series offers various voltage selections ranging from 3.3 to 390 volts. These regulators are specifically engineered for applications where failure cannot be tolerated, leveraging robust glass construction techniques to ensure long-term durability and performance consistency.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 16 V Zener voltage, 5 W power dissipation, and D-5B-2 surface-mount package. Verify that any substitute maintains the same military qualification status and hermetic sealing properties to ensure compatibility with existing high-reliability designs.
