JANTX1N5519CUR-1/TR

Single Zener Diodes Overview

The JANTX1N5519CUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA (SMB) package. It features a nominal Zener voltage of 3.6 V with a tight tolerance of ±2%. The device dissipates up to 500 mW and operates within an extended temperature range from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 3 µA at rated voltage and a Zener impedance of 24 Ω measured at a test current of 20 mA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance on the 3.6 V breakdown voltage.
• Engineered for high-temperature reliability with an operational range extending to +175°C.
• Utilizes a compact surface-mount DO-213AA package suitable for automated assembly processes.

Single Zener Diodes Applications

• Voltage reference circuits in aerospace and defense electronics
• Overvoltage protection stages in harsh environment systems
• Precision regulator networks requiring stable low-voltage references

Single Zener Diodes Procurement Notes

Verify that the specific suffix CUR-1/TR corresponds to the required surface-mount DO-213AA package and tape-and-reel configuration. Confirm compliance with JANTX quality levels and radiation hardness requirements if applicable to the target system. Ensure the manufacturer documentation explicitly supports the intended operating temperature range and power dissipation limits for the final design.

Single Zener Diodes Selection Notes

Select this component when a stable 3.6 V reference is required in space-constrained surface-mount designs. The JANTX grade indicates enhanced screening compared to standard commercial parts, making it suitable for critical applications. Consider the 500 mW power rating and thermal management needs within the PCB layout. Verify compatibility with automated pick-and-place equipment due to the reel packaging format.

Single Zener Diodes Part Context

This part belongs to the JAN1N55xx series of Zener diodes produced by Microchip Technology. The series offers various voltage options in both through-hole and surface-mount packages. The JANTX designation signifies a higher reliability tier, often involving stricter manufacturing controls and testing protocols compared to standard industrial grades, targeting demanding electronic environments.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX1N5519 variants such as JANTX1N5519B-1 or JANTX1N5519CUR-1, provided the package type matches the board layout. Cross-reference with equivalent military-grade Zener diodes from other manufacturers only if pinout and electrical specifications are identical.
