JAN1N6329CUS

Single Zener Diodes Overview

The JAN1N6329CUS is a military-qualified Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 16 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and utilizes an SQ-MELF surface-mount package. Electrical characteristics include a maximum reverse leakage current of 2 µA at the specified test conditions and a Zener impedance of 20 Ω. The component supports a wide operating temperature range from -65°C to +175°C junction temperature, ensuring reliability in demanding environments.

Single Zener Diodes Feature Summary

• Military-grade qualification compliant with MIL-PRF-19500/533 standards
• Surface-mount SQ-MELF package design for compact integration
• Tight voltage tolerance of ±2% for precise regulation
• Extended high-temperature operation capability up to 175°C

Single Zener Diodes Applications

• High-reliability aerospace electronic systems
• Military-grade voltage reference circuits
• Harsh environment power supply regulation
• Critical defense communication equipment

Single Zener Diodes Procurement Notes

Verify that the specific suffix 'CUS' corresponds to the Surface Mount SQ-MELF configuration rather than the axial DO-35 variant found in other JAN1N6329 models. Confirm military qualification status and lot traceability requirements prior to ordering. Ensure compatibility with automated surface-mount assembly processes given the small form factor.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for military applications needing a 16 V reference. Compare against the axial JAN1N6329C if board space permits through-hole mounting. Verify that the 500 mW power rating suffices for the intended circuit load. Check for availability of equivalent JANTX or JANS levels if cost or lead time constraints differ.

Single Zener Diodes Part Context

This part belongs to the 1N63xx series of hermetically sealed glass Zener diodes produced by Microchip. The series offers various voltage options within the 2.4 V to 200 V range. The JAN prefix indicates military qualification, while the CUS suffix specifies the surface-mount SQ-MELF package variant, distinguishing it from standard axial leaded versions.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N6329D (5% tolerance) or JANTX1N6329C (commercial grade). For surface-mount equivalents, verify JANTX1N6329CUS availability. Cross-reference with commercial 1N6329 variants only if military qualification is not mandatory.
