JAN1N3020CUR-1

Single Zener Diodes Overview

The JAN1N3020CUR-1 is a surface mount Zener diode manufactured by Microchip Technology, designed for high-reliability applications. It operates within a junction and storage temperature range of -55°C to +175°C and features a maximum DC power dissipation of 1.0 W. The device utilizes a DO-213AB (MELF) package with a hermetically sealed glass construction. Electrical characteristics include a nominal Zener voltage of 10 V at a test current of 25 mA, a maximum Zener impedance of 7 Ohms, and a maximum reverse leakage current of 25 µA.

Single Zener Diodes Feature Summary

• Hermetically sealed double plug glass construction with metallurgically bonded internal contacts.
• Leadless surface mount MELF package suitable for high-density mounting.
• Qualified per MIL-PRF-19500/115 standards for military reliability levels.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• High-density circuit designs requiring low parasitic characteristics.
• High-reliability environments utilizing radiation-hardened components.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm the 2% voltage tolerance designation. Confirm RoHS compliance status as it may vary by grade. Ensure the ordering quantity matches factory requirements due to potential long production cycles associated with military-grade components.

Single Zener Diodes Selection Notes

Select this component when a 10 V reference is required in a leadless surface mount format. The DO-213AB package offers lower thermal resistance compared to axial equivalents. Verify that the 2% tolerance meets the circuit precision requirements and that the 1 W power rating accommodates the expected thermal load.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series, which are surface mount equivalents of JEDEC registered diodes. The series provides a wide selection of voltages from 6.8 V to 110 V in the same MELF package outline, allowing for standardized inventory management across different voltage references.

Single Zener Diodes Replacement Considerations

Direct replacements include other parts within the 1N3016BUR-1 to 1N3045BUR-1 series or commercial equivalents like the 1N3020B. Verify package compatibility and electrical parameters such as Zener impedance and leakage current before substitution.
