JANTX1N964DUR-1

Single Zener Diodes Overview

The JANTX1N964DUR-1 is a military-qualified Zener diode manufactured by Microchip Technology. It operates in the DO-213AA surface-mount package and provides a nominal voltage of 13 V with a power dissipation rating of 500 mW. The component features a tight tolerance of ±1% and a maximum impedance of 13 Ohms at a test current of 9.5 mA. It supports an extended operating temperature range from -55°C to +175°C and meets MIL-PRF-19500/117 standards for ruggedized applications.

Single Zener Diodes Feature Summary

• Military-grade qualification compliant with MIL-PRF-19500/117 specifications
• High-precision voltage regulation with ±1% tolerance
• Extended thermal stability suitable for harsh environments

Single Zener Diodes Applications

• Precision voltage reference circuits in aerospace systems
• Overvoltage protection in military communication equipment
• Voltage regulation in high-reliability industrial control modules

Single Zener Diodes Procurement Notes

Verify that the specific suffix UR-1 corresponds to the required reel packaging configuration, as standard bulk variants may differ. Confirm RoHS compliance status explicitly, as military qualified versions often deviate from standard environmental directives. Ensure the supplier provides valid traceability documentation and certification consistent with the MIL-PRF-19500/117 requirement for critical procurement channels.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and wide temperature operation are mandatory. The DO-213AA package offers a compact footprint compared to axial leads. Consider the ±1% tolerance against cost constraints, as tighter tolerances increase unit expense. Verify that the 500 mW power rating aligns with the thermal design of the target circuit board layout.

Single Zener Diodes Part Context

This device belongs to the 1N964 series of silicon Zener diodes produced by Microchip. The JANTX designation indicates a screened military grade offering enhanced reliability over commercial equivalents. The part is engineered for durability in demanding operational conditions where standard components might fail due to thermal or electrical stress.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N964DUR-1 for lower screening levels or JANTXV1N964DUR-1 for higher performance grades. Commercial equivalents like 1N964B may lack the necessary military qualification and tolerance precision.
