JAN1N6312DUS

Single Zener Diodes Overview

The JAN1N6312DUS is a military-qualified Zener voltage regulator diode manufactured by Microchip Technology. It features a 3.3 V nominal breakdown voltage with a ±1% tolerance and operates at a test current of 20 mA. The device provides a maximum dynamic impedance of 27 ohms and supports a steady-state power dissipation of 0.5 W. It utilizes a voidless hermetically sealed glass B-SQ MELF surface-mount package, ensuring robust construction for high-reliability applications.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature guide to confirm the exact voltage tolerance and compliance status. Ensure that the procurement specifications align with the required MIL-PRF-19500/533 qualification level. Confirm package dimensions and terminal finish requirements prior to finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a precise 3.3 V reference is required in a surface-mount configuration. The tight 1% voltage tolerance makes it suitable for precision regulation tasks. Consider the B-SQ MELF package for automated assembly processes requiring small footprints while maintaining hermetic sealing standards.

Single Zener Diodes Part Context

This part belongs to the 1N6309US through 1N6355DUS series of 0.5 W Zener diodes. The series offers a wide range of voltages from 2.4 V to 200 V. All variants share the same hermetic glass package and military qualification standards, providing a standardized platform for reliable voltage regulation across different circuit designs.

Single Zener Diodes Replacement Considerations

Direct replacements include other JAN1N6312 variants with identical electrical characteristics but potentially different tolerance suffixes or RoHS compliance statuses. Verify compatibility with existing board layouts due to the specific B-SQ MELF package dimensions.
