JANTXV1N5306UR-1

Current Regulation - Diodes, Transistors Overview

The JANTXV1N5306UR-1 is a current regulator diode manufactured by Microchip Technology, designed for surface-mount applications. It operates within the DO-213AB (MELF) glass package and is qualified to MIL-PRF-19500/463 standards under the JANTXV level. The device provides a regulated current of 2.2 mA with a maximum limiting voltage of 1.95 V. It features a power dissipation rating of 500 mW and utilizes internal metallurgical bonding for reliability.

Current Regulation - Diodes, Transistors Feature Summary

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

Current Regulation - Diodes, Transistors Applications

• Constant current sources in electronic circuits
• Current limiting protection for sensitive components
• Biasing elements in analog signal processing

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 indicates the surface-mount MELF configuration distinct from axial leaded variants. Confirm JANTXV qualification requirements against project specifications. Ensure compatibility with DO-213AB footprint dimensions during PCB layout. Validate that RoHS exemption status aligns with environmental compliance mandates.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise 2.2 mA regulation is required in a compact surface-mount form factor. Compare against the JAN or JANS levels if cost or specific radiation tolerance differs from the JANTXV grade. Ensure the 1.95 V limiting voltage suits the downstream circuit's voltage headroom constraints.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5306 series of current regulator diodes, which offers currents ranging from 0.22 mA to 4.7 mA. The UR-1 suffix specifically denotes the round-end surface-mount variant, contrasting with the axial DO-7 package used in standard 1N5306-1 designs. It serves as a solid-state alternative to Zener diodes for current rather than voltage regulation.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other manufacturers' JANTXV1N5306-1 equivalents in DO-213AB packages. Verify pinout orientation and thermal characteristics match before substitution.
