JANTXV1N5284-1

Current Regulation - Diodes, Transistors Overview

The JANTXV1N5284-1 is a current regulator diode manufactured by Microchip Technology, designed for military and aerospace applications. It operates within the 1N5283-1 through 1N5314-1 series, providing a regulated current of 264 µA with a standard tolerance of ±10%. The device features a maximum power dissipation of 500 mW and an Anode-Cathac voltage rating of 100 V. Qualified per MIL-PRF-19500/463 under the JANTXV level, it utilizes a DO-7 axial leaded package (DO-204AA) suitable for through-hole mounting. The component supports a wide operating temperature range from -65°C to +175°C junction temperature.

Current Regulation - Diodes, Transistors Feature Summary

• High source impedance ensures stable current regulation across broad voltage ranges.
• Internal metallurgical bond construction enhances reliability in harsh environments.
• Double-plug internal bond connection provides robust mechanical stability.

Current Regulation - Diodes, Transistors Applications

• Military electronic systems requiring precise current limiting.
• Aerospace circuits demanding high-reliability constant current sources.
• Temperature-compensated reference circuits utilizing broad voltage operation.

Current Regulation - Diodes, Transistors Procurement Notes

Verify that the ordering suffix matches the required qualification level, as JANTXV denotes specific MIL-PRF-19500/463 standards distinct from commercial or lower-grade variants. Confirm package integrity upon receipt, as axial leads require appropriate handling. Ensure compliance with project-specific environmental requirements, noting that RoHS status may vary by manufacturing lot and grade.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current sink is required over a wide voltage differential rather than voltage regulation. Compare against Zener diodes if the application demands current stability instead of voltage clamping. Verify that the 264 µA output aligns with circuit biasing needs and that the 500 mW power rating accommodates the maximum voltage drop without exceeding thermal limits.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 family of 0.5 W current regulators. The series offers various current values from 0.22 mA to 4.7 mA in standard 10% tolerances. These devices serve as counterparts to Zener diodes, regulating current over a broad voltage range while maintaining similar physical dimensions in axial-leaded packages.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANTXV1N5284-1 units from authorized Microchip distributors. Commercial equivalents like the 1N5284UR-1 lack military qualification. Ensure any replacement maintains the 264 µA nominal current and DO-7 package form factor for direct pin-compatible integration.
