1N6858UR-1

Overview

The 1N6858UR-1 is a small-signal Schottky barrier diode manufactured by Microchip Technology. It is hermetically sealed and metallurgically bonded within a DO-213AA (MELF) glass package. The device is qualified per MIL-PRF-19500/444 standards, offering JAN, JANTX, and JANTXV military grade qualifications for high-reliability applications.

Feature Summary

• Hermetically sealed construction in a DO-213AA glass MELF package
• Metallurgically bonded junction structure
• Qualified to MIL-PRF-19500/444 military reliability standards

Applications

• High-reliability aerospace systems
• Military electronic circuits
• Defense communication equipment

Procurement Notes

Verify the specific qualification level required for your design, as the part series includes JAN, JANTX, and JANTXV grades. Confirm that the DO-213AA package meets your board layout constraints. Ensure procurement channels are authorized to supply components with full traceability documentation required for defense contracts.

Selection Notes

Select this component when a hermetically sealed surface-mount Schottky diode is necessary for harsh environments. The DO-213AA package provides a compact footprint compared to traditional axial leads while maintaining superior sealing properties. Consider the specific voltage and current ratings of the 1N6858 variant against your circuit requirements.

Part Context

This component belongs to a family of Schottky Barrier Diodes that also includes the 1N5711UR-1, 1N5712UR-1, and 1N6857UR-1. Commercial versions of these devices may carry different prefixes, such as CDLL, which do not hold the same military qualification grades. All variants share the same hermetic MELF package construction.
