JANTXV1N5283UR-1

Current Regulation - Diodes, Transistors Overview

The JANTXV1N5283UR-1 is a silicon current regulator diode manufactured by Microchip Technology. It belongs to the MIL-PRF-19500/463 qualified series, specifically designed for high-reliability applications. The device provides a regulated current of 220 µA with a maximum limiting voltage of 1 V. It operates within a temperature range of -65°C to +175°C and features a DO-213AB (MELF) surface-mount package. The component exhibits a minimum dynamic impedance of 25 mΩ and a minimum knee impedance of 2.75 mΩ, ensuring stable current regulation over a broad voltage range.

Current Regulation - Diodes, Transistors Feature Summary

• High source impedance for stable current regulation
• Internal metallurgical bond connection
• Qualified per MIL-PRF-19500/463 standards

Current Regulation - Diodes, Transistors Applications

• Current limiting in sensitive electronic circuits
• Biasing elements in transistor amplifier stages
• Constant current sources for LED drivers

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 indicates the MELF surface-mount package variant distinct from axial leaded versions. Confirm JANTXV qualification level requirements against mission specifications. Ensure compatibility with automated pick-and-place equipment due to the small form factor. Validate RoHS status as military grades may differ from commercial equivalents.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise low-current regulation value near 220 µA is required in a space-constrained design. Compare against axial DO-7 packages if through-hole mounting is mandatory. Consider thermal derating curves for operation above 125°C. Verify that the 500 mW power dissipation rating accommodates the maximum voltage drop across the device.

Current Regulation - Diodes, Transistors 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 JANTXV designation signifies a higher reliability tier within the military qualification spectrum.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANTXV1N5283UR-1 units from authorized distributors. Cross-reference with JAN or JANS levels if lower qualification tiers are acceptable. Commercial equivalents lack the specified radiation hardness and extended temperature performance.
