1N826/TR

Single Zener Diodes Overview

The Microchip Technology 1N826/TR is a temperature-compensated Zener reference diode belonging to the 1N821 through 1N829 series. It provides nominal voltage options of 6.2 V and 6.55 V with a tolerance of ±5%. Designed for operation at a test current of 7.5 mA, it achieves low temperature coefficients as minimal as 0.0005%/°C. The device features internal metallurgical bonds and is housed in a DO-35 axial-leaded glass package. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Temperature compensated design ensuring minimal voltage change across broad temperature ranges
• Internal metallurgical bonds for structural integrity
• Available in smaller axial-leaded DO-35 package configuration

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding high voltage stability
• Precision analog signal processing applications

Single Zener Diodes Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and qualification level. Ensure the ordering code matches the required voltage tolerance and temperature coefficient specifications. Confirm availability status directly with authorized distributors as supply levels vary. Validate that the component meets all necessary environmental and reliability standards for the intended deployment environment.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 6.2 V or 6.55 V is required with minimal drift over temperature. Consider the DO-35 package constraints for PCB layout. Evaluate if the specified temperature coefficient meets the system's precision requirements compared to standard Zener diodes. Verify compatibility with the 7.5 mA operating current condition for optimal performance.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N821 through 1N829 series of Zero-TC Reference Diodes manufactured by Microchip Technology (formerly Microsemi). The series offers both 6.2 V and 6.55 V nominal voltages. Military qualified versions are available with JAN, JANTX, JANTXV, or JANS prefixes. Radiation-hardened equivalents exist under the RH prefix.

Single Zener Diodes Replacement Considerations

Check for direct military equivalents such as JANTX1N826TR-1. Surface mount alternatives may be found in the DO-213AA package with UR-1 suffixes. Consult factory data for radiation-hardened RH826 variants if applicable.
