JANTXV1N5289-1

Overview

The JANTXV1N5289-1 is a current regulator diode manufactured by Microchip Technology. It operates within a temperature range of -65°C to +175°C and features a DO-35 axial through-hole package. The device provides a maximum regulated current of 473µA with a maximum power dissipation of 500mW. Key electrical specifications include a maximum anode-to-cathode voltage (Vak) of 100V and a maximum limiting voltage of 1.05V. The component utilizes silicon as the primary semiconductor material and is designed for single configuration applications.

Feature Summary

• Maintains stable current regulation across extreme environmental conditions ranging from -65°C to +175°C junction temperature.
• Utilizes metallurgically bonded construction for enhanced reliability in harsh environments.
• Provides isolated case connection suitable for direct mounting to heat sinks or chassis ground.

Applications

• Precision constant current sources for sensitive analog circuits
• Biasing elements for transistors and active components requiring stable operating points
• Protection circuits limiting current flow to prevent component damage

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates the exact qualification level and packaging format required for your application. Confirm that the procurement channel provides appropriate traceability documentation, including lot codes and material certifications, to ensure compliance with aerospace or military standards associated with this product line.

Selection Notes

Select this component when a fixed low-current regulation value near 473µA is required without complex external feedback networks. Ensure the circuit design accommodates the maximum 100V reverse voltage rating and that the thermal management strategy supports the 500mW power dissipation limit under worst-case operating conditions.

Part Context

This part belongs to the broader 1N5289 series of current regulator diodes produced by Microchip Technology. Variants within this family typically share similar physical dimensions and basic operational principles but differ in specific current regulation values and voltage ratings. The JANTXV prefix denotes a specific high-reliability qualification tier distinct from commercial or standard industrial grades.

Replacement Considerations

Direct functional substitutes may include other 1N5289-series parts from different manufacturers if current and voltage ratings match exactly. Verify pinout compatibility and package dimensions before substitution. Cross-reference datasheets to ensure equivalent temperature coefficients and dynamic impedance characteristics are maintained in the new component.
