JANTXV1N5291-1/TR

Overview

The JANTXV1N5291-1/TR is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 (DO-204AA) axial leaded package. It provides a regulated current of 616 µA with a maximum peak operating voltage of 100 V and a power dissipation rating of 500 mW. The device features a maximum limiting voltage of 1.55 V and operates within a temperature range of -65°C to +175°C. This component is qualified per MIL-PRF-19500/463 under the JANTXV level, ensuring reliability for demanding applications.

Feature Summary

• Provides stable current regulation over a broad voltage range
• Qualified for high-reliability military environments
• Features internal metallurgical bond connection

Applications

• Current limiting circuits
• Biasing networks for transistors and ICs
• Constant current sources for sensors

Procurement Notes

Verify the specific suffix configuration against the manufacturer's datasheet to ensure compatibility with required qualification levels. Confirm that the reel packaging matches the automated assembly requirements. Cross-reference the part number with the latest Microchip documentation to validate any potential design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a precise constant current source is required across varying load voltages. Ensure the circuit design accommodates the 100 V maximum operating voltage and 500 mW power dissipation limits. Verify that the DO-7 package dimensions fit the available PCB space and that the thermal environment supports the specified wide operating temperature range without exceeding junction limits.

Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. These devices serve as counterparts to Zener diodes, regulating current rather than voltage. The series offers various current values from 0.22 mA to 4.7 mA in standard tolerances, providing designers with flexible options for current control applications in axial-leaded packages.

Replacement Considerations

Compatible substitutes include other JANTXV-qualified current regulator diodes from the same series, such as the JAN1N5291-1 or commercial equivalents like the 1N5291, provided the electrical parameters match the application requirements.
