JANS1N4132UR-1/TR

Single Zener Diodes Overview

The JANS1N4132UR-1/TR is a high-reliability Zener diode manufactured by Microchip Technology. It operates in the surface-mount DO-213AA-2 package, also known as MELF. The device provides a nominal Zener voltage of 82 V with a power dissipation rating of 500 mW. It features a tight voltage tolerance of 1% and a maximum noise density of 40 μV/√Hz for voltages of 6.8 V and above. The component is qualified to the JANS level under MIL-PRF-19500/435, ensuring suitability for demanding environments. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• JANS qualification ensures compliance with MIL-PRF-19500/435 standards for high reliability applications.
• Internal metallurgical bond construction enhances structural integrity and thermal performance.
• Surface mount design offers a direct equivalent to registered through-hole series components.

Single Zener Diodes Applications

• High-reliability aerospace electronic systems
• Military-grade circuit protection networks
• Precision voltage regulation in harsh environments

Single Zener Diodes Procurement Notes

Verify that the specific suffix UR-1/TR corresponds to the reel packaging configuration required for automated assembly processes. Confirm that the JANS qualification level meets the specific project reliability requirements, as this denotes space-grade or military-grade screening distinct from commercial JAN variants. Ensure the 1% tolerance specification aligns with the circuit's precision needs.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for circuits previously designed around through-hole Zener diodes. The 82 V rating and 500 mW dissipation must match the load conditions. Consider the low noise characteristic if the application involves sensitive signal processing. Verify that the DO-213AA footprint is available on the target PCB layout.

Single Zener Diodes Part Context

This part belongs to the 1N4099 through 1N4135 series of metallurgically bonded glass surface mount Zener diodes. It serves as the surface-mount counterpart to traditional axial leaded equivalents. The JANS designation indicates it has undergone rigorous screening and testing protocols defined by military specifications, distinguishing it from standard industrial grade devices.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent replacements include JAN1N4132UR-1 and JANTXV1N4132UR-1. These variants share the same electrical characteristics but differ in their specific qualification levels and screening intensity. Verify package compatibility before substitution.
