JAN1N6319DUS

Single Zener Diodes Overview

The JAN1N6319DUS is a military-qualified Zener voltage regulator from the 1N6309US through 1N6355DUS series, manufactured by Microchip Technology. It features a 6.2 V nominal Zener voltage with a tight ±1% tolerance and operates at a test current of 20 mA. The device provides a maximum power dissipation of 0.5 W and exhibits a dynamic impedance of 3 Ohms. It utilizes a voidless hermetically sealed glass B-SQ MELF surface-mount package with internal metallurgical bonds. The component supports an operating temperature range from -65 °C to +175 °C and meets MIL-PRF-19500/533 reliability standards.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless-glass construction with tungsten slugs for high-reliability environments
• Internal metallurgical bonds ensuring robust mechanical integrity
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard design suitable for space applications

Single Zener Diodes Applications

• High-reliability aerospace systems where failure cannot be tolerated
• Military-grade electronic circuits requiring strict voltage regulation
• Radiation-hardened instrumentation and control modules

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required reliability level (JAN) and voltage tolerance (D suffix for 1%). Confirm RoHS compliance status as it applies only to commercial grades; this military variant typically lacks RoHS certification. Ensure the ordering documentation explicitly references MIL-PRF-19500/533 qualification requirements to guarantee authenticity and traceability.

Single Zener Diodes Selection Notes

Select the JAN1N6319DUS when a precise 6.2 V reference is needed in a compact surface-mount form factor. The D suffix indicates a tighter 1% voltage tolerance compared to standard 5% variants. Consider the B-SQ MELF package dimensions for PCB layout constraints. Verify thermal derating curves if operating near the maximum junction temperature limits.

Single Zener Diodes Part Context

This component belongs to the industry-standard 1N6309 through 1N6355 series of 0.5 W Zener diodes. The JAN prefix denotes a specific military reliability level qualified under MIL-PRF-19500/533. The series offers extensive voltage selections ranging from 2.4 V to 200 V, providing designers with standardized options for various regulation needs across different tolerance classes.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTX1N6319DUS and JANTXV1N6319DUS, which share identical electrical characteristics but differ in reliability screening levels. Commercial equivalents like 1N6319DUS lack military qualification. Cross-reference datasheets to confirm package compatibility and verify that alternative suppliers meet the same MIL-PRF-19500/533 standards.
