JANTXV1N5313-1

Overview

The JANTXV1N5313-1 is a silicon current regulator diode manufactured by MACOM Technology Solutions. It belongs to the 1N5283UR-1 through 1N5314UR-1 series of 0.5-watt current regulators, providing a regulated current of 3.6 mA with standard 10% tolerance. The device operates within a broad voltage range and features high source impedance for stable regulation. It is housed in a DO-213AB (MELF-2) package with an internal metallurgical bond connection. The component is qualified under the JANTXV grade per MIL-PRF-19500/463 standards.

Feature Summary

• High source impedance ensures stable current regulation over a wide operating voltage range.
• Internal metallurgical bond provides robust mechanical integrity and reliability.
• Qualified to JANTXV specifications per MIL-PRF-19500/463 for demanding environments.

Applications

• Constant current sources for biasing semiconductor devices.
• Current limiting protection in sensitive electronic circuits.
• Reference current generation in analog signal processing systems.

Procurement Notes

Verify the specific JANTXV qualification status against the latest MIL-PRF-19500/463 revision when sourcing. Confirm that the DO-213AB MELF package orientation matches the circuit design requirements. Ensure the supplier provides traceability documentation for the metallurgical bond construction to guarantee compliance with the specified military-grade reliability standards.

Selection Notes

Select this component when a precise 3.6 mA regulation is required with high impedance characteristics. The JANTXV grade offers tighter performance tolerances compared to lower grades. Consider the 0.5 W power dissipation limit and the thermal resistance of the MELF package when designing the heat management strategy for the application environment.

Part Context

This part is part of MACOM's extensive portfolio of discrete semiconductors designed for high-reliability applications. The 1N53xxUR-1 series complements other current regulator and Zener diode offerings from the manufacturer. These components are typically utilized in aerospace, defense, and industrial sectors where long-term stability and ruggedness are critical operational requirements.

Replacement Considerations

Direct substitutes include other JANTXV qualified current regulators from the same series, such as the JANTXV1N5312-1 or JANTXV1N5314-1, provided the current rating differences are acceptable. Verify pinout compatibility and package dimensions before substitution.
