JAN1N746C-1/TR

Single Zener Diodes Overview

The JAN1N746C-1/TR is a military-grade Zener diode manufactured by Microchip Technology. It features a nominal voltage of 3.3 V with a tight tolerance of ±2%. The component is rated for a maximum power dissipation of 500 mW and operates within an extended temperature range of -65°C to 175°C. It utilizes a surface-mount DO-213AA (MELF) glass package and is supplied in tape and reel format.

Single Zener Diodes Feature Summary

• Military qualification per MIL-PRF-19500/127
• Tight voltage tolerance of ±2%
• Extended operating temperature range

Single Zener Diodes Applications

• Precision voltage regulation in harsh environments
• Reference voltage sources for military electronics
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets, as packaging variations exist between bulk and tape-and-reel formats. Confirm that the JAN prefix meets the required screening levels for your application. Ensure compatibility with the DO-213AA footprint during PCB layout. Check for RoHS exemptions if applicable to your project requirements.

Single Zener Diodes Selection Notes

Select this component when a stable 3.3 V reference is required under extreme thermal conditions. The ±2% tolerance offers higher precision than standard commercial equivalents. The MELF package provides robustness for automated assembly processes. Consider the JANTX variant if lower screening costs are acceptable without compromising reliability.

Single Zener Diodes Part Context

This part belongs to the 1N746 series of 0.5 W Zener regulators. It serves as the surface-mount equivalent to axial-leaded versions. The JAN prefix denotes full military qualification. The -1 suffix indicates internal metallurgical bonding. The UR-1 or TR suffix specifies the tape-and-reel packaging format.
