2N6317

Overview

The Microchip Technology 2N6317 is a hermetically sealed single Zener diode designed for high-reliability applications. It features a nominal Zener voltage of 5.1 V with a 5% tolerance and operates within an extended temperature range from -65°C to +175°C. The device utilizes a DO-35-2 axial leaded package, dissipating up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 14 Ohms at a test current of 20 mA, and a forward voltage of 1.4 V.

Feature Summary

• Hermetically sealed construction ensures long-term stability in harsh environments
• Extended thermal capability supports operation up to 175°C
• Low leakage current maintains circuit integrity under reverse bias

Applications

• Military aerospace voltage regulation circuits
• High-temperature industrial sensor protection
• Spacecraft reference voltage generation

Procurement Notes

Verify the specific suffix (e.g., TR or D) against the official datasheet to confirm packaging format, as this affects handling and storage requirements. Confirm RoHS exemption status is acceptable for the target assembly process. Ensure the procurement channel provides traceability documentation required for qualified components.

Selection Notes

Select this component when a stable 5.1 V reference is required in extreme thermal conditions. The DO-35 package suits through-hole designs where space permits. Compare the 14 Ohm impedance against load requirements to ensure adequate regulation performance without excessive power dissipation during normal operation.

Part Context

This part belongs to the military-grade Zener diode family manufactured by Microchip Technology. It shares the core electrical specifications of commercial variants but differs in manufacturing processes that guarantee hermetic sealing and radiation hardness suitable for defense and space sectors.
