JAN1N3039CUR-1

Single Zener Diodes Overview

The JAN1N3039CUR-1 is a surface-mount Zener diode manufactured by Microchip Technology, qualified to MIL-PRF-19500/115 standards. It features a DO-213AB (MELF) package with hermetically sealed glass construction and metallurgically bonded terminals. The device provides a nominal Zener voltage of 62 V at a test current of 4.0 mA, with a maximum dynamic impedance of 125 Ohms at the knee current. It supports a DC power dissipation of 1.0 W and operates within a junction temperature range of -55°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed double plug glass construction for high reliability
• Metallurgically enhanced internal contact design for lower thermal resistance
• Leadless surface mount MELF package suitable for high-density applications
• Qualified under JAN, JANTX, and JANTXV military levels

Single Zener Diodes Applications

• Voltage regulation in high-reliability electronic circuits
• High-density surface mount assembly environments
• Applications requiring low parasitic characteristics

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'C' corresponds to the specific 2% tolerance level required for the application. Confirm the package outline matches the DO-213AB specification. Ensure the procurement source provides documentation confirming qualification per MIL-PRF-19500/115 for the JAN grade. Check for any specific handling requirements associated with glass MELF packages.

Single Zener Diodes Selection Notes

Select this component when a 62 V reference is needed in a leadless surface-mount form factor. The 2% tolerance offers tighter voltage control compared to standard commercial grades. Consider the 1.0 W power rating and thermal derating curve for heat management. Verify compatibility with the mounting surface coefficient of expansion to prevent mechanical stress during thermal cycling.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series, which are surface-mount equivalents of JEDEC registered axial diodes. The series covers a Zener voltage range from 6.8 V to 110 V. The JAN1N3039CUR-1 specifically utilizes the 'C' suffix to denote a 2% voltage tolerance, distinguishing it from the 'B' (5%) and 'D' (1%) variants within the same family.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' parts meeting the DO-213AB outline and MIL-PRF-19500/115 qualification. Equivalent JEDEC types such as 1N3039B may be considered if axial packaging is acceptable. Verify that substitute parts maintain the 62 V nominal voltage and 2% tolerance specifications.
