JANTX1N5314UR-1

Current Regulation - Diodes, Transistors Overview

The JANTX1N5314UR-1 is a silicon current regulator diode manufactured by Microchip Technology. It provides a regulated current of 4.7 mA with a maximum limiting voltage of 2.9 V. The device operates within a temperature range of -55 °C to +175 °C and is housed in a hermetically sealed DO-213AB (MELF) glass package. Qualified under MIL-PRF-19500/463, it serves as a surface-mount alternative to axial-leaded current regulators.

Current Regulation - Diodes, Transistors Feature Summary

• Hermetically sealed glass MELF construction for environmental protection
• Constant current regulation over a broad operating voltage range
• Military qualification per MIL-PRF-19500/463 standards

Current Regulation - Diodes, Transistors Applications

• Current limiting in high-reliability electronic circuits
• Biasing elements for transistor amplifier stages
• Reference current sources in precision instrumentation

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 against the official datasheet to confirm the round-end terminal configuration and hermetic seal integrity. Ensure the procurement order explicitly states the JANTX quality level to guarantee compliance with MIL-PRF-19500/463 requirements. Confirm RoHS exemption status prior to integration into restricted substance-controlled assemblies.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable 4.7 mA current source is required in a compact surface-mount form factor. The DO-213AB package suits automated assembly processes while maintaining military-grade reliability. Verify that the circuit's minimum operating voltage exceeds the 2.9 V limiting voltage to ensure proper regulation functionality.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. The JANTX designation indicates a screened military grade offering tighter parameter tolerances than standard JAN parts. The UR-1 suffix specifies the MELF package variant with round ends, distinct from axial leaded versions.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANTX1N5314 variants with identical electrical characteristics but different packaging options. Cross-reference with commercial equivalents only if military qualification and hermetic sealing are not mandatory for the application.
