1N5301-1

Overview

The JAN1N5301UR-1 is a surface-mount current regulator diode manufactured by Microchip Technology. It utilizes the DO-213AB (MELF, LL41) glass package and belongs to the MIL-PRF-19500/463 military series. The device functions as a silicon current regulator with a nominal regulation current of 1.4 mA. It supports a peak operating voltage range from -55°C to +200°C junction temperature. The component is designed for steady-state power dissipation at lead temperatures up to 75°C, with derating required above this threshold.

Feature Summary

Military-grade reliability compliant with MIL-PRF-19500/463 standards
Surface-mount MELF glass encapsulation for compact integration
Silicon-based current regulation functionality

Applications

Constant current biasing in military electronic circuits
Current limiting protection in aerospace systems
Stabilization of reference currents in harsh environments

Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm the exact variant and compliance status. Ensure that the procurement channel provides traceability to the MIL-PRF-19500/463 standard. Confirm the package type matches the DO-213AB specification before finalizing orders.

Selection Notes

Select this component when a surface-mount current regulator with military qualification is required. Compare the 1.4 mA regulation current against circuit requirements. Evaluate the thermal derating characteristics relative to the maximum lead temperature of 75°C. Ensure the DO-213AB footprint aligns with the PCB layout constraints.

Part Context

This part is a specialized variant within the broader 1N5301 family, distinguished by its surface-mount MELF packaging and military certification. While standard 1N5301 devices often utilize axial through-hole packages like DO-7, the JAN1N5301UR-1 adapts the same core silicon technology for modern surface-mount assembly processes.

Replacement Considerations

Direct replacements must match the 1.4 mA regulation current and DO-213AB package. Verify if alternative manufacturers offer MIL-PRF-19500/463 qualified equivalents. Cross-reference electrical parameters such as knee impedance and maximum limit voltage to ensure functional compatibility.
