Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 indicates the tape-and-reel packaging variant if reel supply is required, as bulk packaging may differ. Confirm that the JAN prefix denotes full military qualification under MIL-PRF-19500/463. Ensure the DO-213AB MELF package matches the footprint constraints. Validate that the 330 µA regulation current meets the circuit design requirements without external components.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when hermetic sealing and high-temperature stability are critical for space or defense applications. Compare the 330 µA regulation point against alternative current regulator diodes if different bias currents are needed. Verify that the 100 V peak voltage rating exceeds the maximum transient voltages present in the target circuit. Consider the MELF package size relative to available PCB real estate.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5286 series of current regulator diodes produced under military specifications. The JAN prefix signifies compliance with MIL-PRF-19500/463, while the TX suffix typically indicates enhanced screening levels compared to the standard JAN grade. The UR-1 suffix generally denotes reel packaging for automated assembly processes.

Current Regulation - Diodes, Transistors Replacement Considerations

JAN1N5286UR-1 serves as the standard military-grade equivalent with potentially different screening levels. JANTXV1N5286UR-1 offers higher reliability screening. For non-hermetic surface-mount needs, verify compatibility with commercial equivalents, though MIL-PRF-19500/463 compliance is unique to the JAN/TX family.
