JAN1N4492CUS/TR

Single Zener Diodes Overview

The Microchip Technology JAN1N4492CUS/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 130 V. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5 W at 25°C ambient. The device features a maximum dynamic impedance of 500 Ohms at the test current of 1.9 mA, with a maximum reverse leakage current of 0.25 µA at 104 V. It utilizes an A (D-5A) MELF package and holds JANTXV qualification per MIL-PRF-19500/406.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction with internal metallurgical bonds for high reliability.
• Triple-layer passivation provides robust protection against environmental stressors.
• Inherently radiation hard and non-sensitive to electrostatic discharge.
• Surface mount equivalent of popular JEDEC registered series.

Single Zener Diodes Applications

• High-reliability military applications where failure cannot be tolerated.
• Voltage regulation over broad operating current and temperature ranges.
• Circuit protection in harsh environments requiring radiation hardness.

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level and RoHS compliance status. Confirm the package type corresponds to the D-5A MELF form factor. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability for military-grade components.

Single Zener Diodes Selection Notes

Select this component when a 130 V Zener reference is required in a surface mount configuration. The JANTXV grade ensures strict parameter control suitable for critical systems. Consider the 1.5 W power dissipation capability and thermal resistance characteristics during circuit layout to maintain safe operating temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5 Watt glass Zener diodes. These devices are designed as surface mount replacements for axial lead equivalents, offering identical electrical performance in a compact footprint. The series covers a wide voltage range from 3.3 V to 200 V with various tolerance options.

Single Zener Diodes Replacement Considerations

Direct functional substitutes include other JANTXV qualified parts within the same 1N44xxUS series family. Verify pinout compatibility and physical dimensions if replacing with commercial grade variants. Cross-reference with JAN or JANTX levels only if relaxed parameter tolerances are acceptable for the application.
