JANTX1N3031CUR-1/TR

Single Zener Diodes Overview

The JANTX1N3031CUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 30 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and exhibits a maximum impedance of 40 Ohms. Reverse leakage current is specified at 10 µA when tested at 22.8 V. The component utilizes the DO-213AB (MELF, LL41) surface mount package and supports an operating temperature range from -55°C to 175°C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 30 V nominal breakdown voltage and ±2% tolerance.
• Engineered for high-temperature reliability with an extended operating range up to 175°C.
• Utilizes a compact MELF surface-mount package suitable for automated assembly processes.

Single Zener Diodes Applications

• Voltage reference circuits in military-grade electronic systems
• Overvoltage protection stages requiring high thermal stability

Single Zener Diodes Procurement Notes

Verify that the specific suffix CUR-1/TR corresponds to the required MELF package and tape-and-reel configuration. Confirm compliance with MIL-PRF-19500/115 qualification standards if military specifications are mandatory. Ensure the procurement documentation explicitly states the RoHS non-compliant status to meet regulatory requirements for the intended deployment environment.

Single Zener Diodes Selection Notes

Select this component when a 30 V Zener voltage with strict ±2% tolerance is required in a surface-mount form factor. The 1 W power rating and 175°C maximum junction temperature make it suitable for demanding thermal environments. Compare against through-hole equivalents like the JANTXV1N3031C-1 if PCB layout constraints allow for larger packages.

Single Zener Diodes Part Context
