1N3156E3/TR

Overview

The Microchip Technology 1N3156E3/TR is a temperature compensated Zener reference diode with an 8.4V nominal voltage and a maximum temperature coefficient of 0.002%/°C. It operates at a test current of 10mA, features a maximum impedance of 15Ω, and dissipates up to 500mW. The device utilizes a hermetically sealed glass DO-7 (DO-204AA) package with axial leads and RoHS compliant annealed matte-Tin plating.

Feature Summary

• Provides minimal voltage changes over a broad temperature range
• Features internal metallurgical bonds for reliability
• Offers flexible axial-lead mounting terminals

Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low voltage drift with temperature

Procurement Notes

Verify the specific suffix requirements for tape and reel packaging when ordering. Confirm that the e3 designation aligns with RoHS compliance needs for your assembly process. Ensure the manufacturer documentation matches the intended military or commercial qualification levels if applicable.

Selection Notes

Select this component for applications requiring tight voltage stability across wide temperature variations. Consider the operating current impact on temperature coefficients using provided graphs. Evaluate the package constraints against available board space for axial leaded components.

Part Context

This part belongs to the 1N3154 through 1N3157A series of Zero-TC Reference Diodes. The series provides various temperature coefficient options around the 8.4V nominal voltage. The e3 suffix indicates RoHS compliance, while TR denotes tape and reel packaging availability.

Replacement Considerations

Consult factory data for Radiation Hardened equivalents designated with the RH prefix. Military versions are available with JAN, JANTX, or JANTXV prefixes.
