1N6857UR-1

Overview

The Microchip Technology 1N6857UR-1 is a small-signal Schottky barrier diode designed for high-reliability applications. It features a single silicon element housed in a hermetically sealed DO-213AA glass package, also known as LL34 or MELF-2. The device is metallurgically bonded and qualified per MIL-PRF-19500/444 standards. Key electrical parameters include a maximum repetitive reverse voltage of 20V, an average rectified forward current of 0.15A, and a maximum forward voltage of 0.35V. It operates within a junction temperature range of -65°C to +150°C.

Feature Summary

Hermetically sealed construction in a DO-213AA glass package ensures environmental protection and long-term stability.
Metallurgical bonding provides robust mechanical integrity suitable for demanding environments.
Military-grade qualification aligns with MIL-PRF-19500/444 specifications for high reliability.

Applications

High-reliability aerospace systems
Military electronic circuits
Harsh environment signal processing

Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your design, as the base part number may have suffix variants. Confirm RoHS compliance status, as military versions often differ from commercial equivalents. Ensure the ordering documentation explicitly references the MIL-PRF-19500/444 standard to guarantee the correct hermetic sealing and metallurgical bonding characteristics are delivered.

Selection Notes

Select this component when a hermetically sealed Schottky diode with low forward voltage drop is required for critical applications. The DO-213AA package is suitable for surface mount assembly where space is constrained but reliability is paramount. Consider the 20V reverse voltage rating and 0.15A current capacity to ensure adequate headroom for the specific circuit requirements.

Part Context

This diode belongs to a series that includes related variants such as the 1N5711UR-1, 1N5712UR-1, and 1N6858UR-1. These components share similar Schottky barrier technologies and packaging styles but differ in voltage and current ratings. The CDLL prefix equivalents exist but typically lack the military qualification grades available with the JAN/JANTX prefixes.
