JANTXV1N5290-1

Overview

The JANTXV1N5290-1 is a high-reliability silicon current regulator diode manufactured by Microchip Technology. It provides a constant current output of 517 µA with a maximum limiting voltage of 100 V and a power dissipation rating of 500 mW. The device operates within a temperature range of -55°C to +175°C and utilizes the DO-204AA (DO-7) axial-leaded through-hole package. This component belongs to the JANTXV qualification level, ensuring strict performance standards for demanding environments.

Feature Summary

• Maintains stable current regulation across a wide operating voltage range
• Hermetically sealed construction for enhanced environmental protection
• Designed for operation in extreme temperature conditions

Applications

• Constant current sources for LED biasing
• Current limiting in sensitive electronic circuits
• High-reliability aerospace and defense systems

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm the exact qualification level and package variant. Ensure that the procurement channel provides traceability certificates required for JANTXV grade components. Confirm compliance with relevant military specifications before finalizing orders.

Selection Notes

Select this component when a precise, low-current regulation value is required in harsh environments. Compare the 517 µA specification against circuit requirements to ensure compatibility. Consider the thermal management capabilities of the DO-7 package relative to the 500 mW power dissipation limit during design.

Part Context

This part is part of the 1N5283-1 through 1N5314-1 series of current regulator diodes. These devices serve as counterparts to Zener diodes, regulating current over a broad voltage range rather than voltage over a broad current range. The series offers various current values in standard tolerances.

Replacement Considerations

Compatible replacements include other manufacturers' 1N5290 equivalents or members of the 1N5283-1 series with matching current ratings. Verify pinout compatibility and thermal characteristics when substituting.
