JAN1N5308UR-1

Current Regulation - Diodes, Transistors Overview

The JAN1N5308UR-1 is a silicon current regulator diode manufactured by Microchip Technology. It operates in the DO-213AB (MELF) surface-mount package with two terminals and an isolated case connection. The device provides a nominal regulating current of 2.7 mA with a maximum limiting voltage of 2.15 V. It is qualified under MIL-PRF-19500/463G standards for military applications.

Current Regulation - Diodes, Transistors Feature Summary

• High source impedance for stable current regulation
• Internal metallurgical bond construction
• Military qualification per MIL-PRF-19500/463

Current Regulation - Diodes, Transistors Applications

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

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific revision level against MIL-PRF-19500/463G requirements during acquisition. Confirm that the DO-213AB MELF package matches the design footprint. Ensure the manufacturer documentation explicitly lists JAN1N5308UR-1 as the part number to avoid confusion with commercial variants or axial-leaded equivalents like the JAN1N5308-1.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 2.7 mA current regulation is required within a surface-mount design. The 2.15 V limiting voltage defines the minimum operating headroom. Compare against other series members such as JANTX1N5308UR-1 if different quality levels are acceptable, noting that the JAN grade ensures strict adherence to military performance specifications.

Current Regulation - Diodes, Transistors Part Context

This device belongs to the 1N5283UR-1 through 1N5314UR-1 series of 0.5 watt current regulators. These devices offer a selection of currents ranging from 0.22 mA to 10 mA in standard 10% tolerances. The series serves as a counterpart to Zener diodes, regulating current over a broad voltage range rather than voltage over a broad current range.

Current Regulation - Diodes, Transistors Replacement Considerations

JANTX1N5308UR-1 is a verified substitute within the same family offering similar electrical characteristics but potentially different qualification levels.
