JAN1N3038DUR-1/TR

Single Zener Diodes Overview

The JAN1N3038DUR-1/TR is a surface mount Zener diode from the 1N3016BUR-1 to 1N3045BUR-1 series, manufactured by Microchip Technology. It features a DO-213AB (MELF) package and is qualified per MIL-PRF-19500/115 for JAN reliability levels. The device provides a nominal Zener voltage of 56 V at a test current of 4.5 mA, with a maximum dynamic impedance of 110 Ohms. It operates within a junction temperature range of -55°C to +175°C and dissipates up to 1 W of power.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF construction with metallurgically bonded internal contacts for high-reliability performance.
• Qualified under MIL-PRF-19500/115 standards for JAN military reliability levels.
• Leadless surface mount design suitable for high-density applications with low parasitic requirements.

Single Zener Diodes Applications

• Voltage regulation in high-density electronic circuits
• High-reliability aerospace and defense systems
• Circuits requiring radiation-hardened components

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the /TR suffix to confirm tape and reel packaging, as bulk packaging options exist for this series. Ensure the JAN qualification level meets project requirements, as JANTX and JANTXV variants are also available. Confirm RoHS compliance status if required, noting that commercial versions may differ from military-grade specifications.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, leadless surface mount Zener diode is required for harsh environments. The JAN qualification ensures adherence to strict military reliability standards. Consider the 56 V nominal voltage and 110 Ohm impedance characteristics against circuit load requirements. Verify thermal management needs given the 1 W power dissipation rating and derating curve above 125°C.

Single Zener Diodes Part Context

This device belongs to the 1N3016B-1 through 1N3045B-1 JEDEC registered series adapted for surface mount technology. It serves as a direct replacement for axial-leaded equivalents while offering improved mounting density. The series covers a wide Zener voltage range from 6.8 V to 110 V, providing versatile options for various voltage regulation needs in ruggedized electronics.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTX1N3038BUR-1 and JANTXV1N3038BUR-1, which share identical electrical characteristics but offer different reliability qualification levels. Commercial grade versions such as 1N3038BUR-1 are functionally similar but lack military qualification. Ensure package compatibility when substituting with other MELF-style diodes.
