JANTXV1N829-1

Single Zener Diodes Overview

The JANTXV1N829-1 is a temperature-compensated Zener reference diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.2 V with a tolerance of ±5%. The device operates at a test current of 7.5 mA and has a maximum power dissipation of 500 mW. It exhibits a Zener impedance of 15 Ohms and a maximum reverse leakage current of 2 µA. The component is housed in a DO-35-2 through-hole package and supports an operating temperature range from -55 °C to +175 °C.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad temperature ranges
• Military qualification to MIL-PRF-19500/159 under the JANTXV quality level
• Internal metallurgical bonds for enhanced reliability

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Electronic designs demanding low temperature coefficient performance
• Radiation-hardened applications utilizing total dose radiation guarantees

Single Zener Diodes Procurement Notes

Verify that the ordering suffix correctly identifies the JANTXV military grade level, as prefixes and suffixes define specific qualification standards. Confirm compliance requirements, noting that this component does not meet RoHS specifications. Ensure the procurement documentation explicitly references MIL-PRF-19500/159 to validate the radiation hardening and quality assurance levels associated with this specific part number.

Single Zener Diodes Selection Notes

Select this component when a precise 6.2 V reference with tight temperature stability is required for harsh environments. The JANTXV designation ensures higher reliability than standard commercial grades. Consider the DO-35-2 package constraints for board layout. Evaluate if the specified 500 mW power dissipation meets the thermal requirements of the target application circuit.

Single Zener Diodes Part Context

This device belongs to the 1N821 through 1N829 series of zero-temperature-coefficient reference diodes. These components are designed to provide stable voltage references with coefficients as low as 0.0005%/°C. The series includes both 6.2 V and 6.55 V options, with the 1N829 variant specifically offering the 6.2 V nominal output suitable for precision analog applications.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N829-1, JANTX1N829-1, and JANS1N829-1, which share the same electrical characteristics but differ in military qualification levels. Surface mount equivalents are available with the UR-1 suffix, such as JANTXV1N829UR-1.
