JANS1N4618C-1/TR

Single Zener Diodes Overview

The JANS1N4618C-1/TR is a hermetically sealed glass Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 2.7 V with a tight tolerance of ±2%. The device has a power dissipation rating of 500 mW (0.5 W) and operates in the Through Hole package DO-204AH (DO-35). It is designed for voltage regulation applications requiring high reliability.

Single Zener Diodes Feature Summary

• Hermetically sealed glass case construction
• High precision voltage regulation with ±2% tolerance
• Military-grade radiation hardness qualification

Single Zener Diodes Applications

• Military aerospace systems
• Radiation-hardened electronic circuits
• Precision voltage reference sources

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the ±2% tolerance variant, distinct from standard versions. Confirm RoHS status as non-compliant due to military specifications. Ensure procurement channels support traceability requirements for defense contracts. Check for recent Product Change Notifications affecting lead times or material composition.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and radiation tolerance are required. The DO-35 package suits through-hole mounting constraints. Compare against JANS1N4618-1 if ±5% tolerance is acceptable. Ensure thermal management supports 500 mW dissipation in the target enclosure environment.

Single Zener Diodes Part Context

This part belongs to the JAN series of radiation-hardened discrete semiconductors. It is a specialized variant of the standard 1N4618 diode, enhanced for harsh environments. The 'S' denotes space/military grade, while 'C' specifies the tighter voltage binning compared to standard commercial equivalents.
