Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 confirms the surface-mount MELF configuration and military grade qualification. Confirm RoHS status as non-compliant due to lead content. Ensure the ordering part number matches the required current tolerance and voltage ratings specified in the official datasheet before procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount solution is required for constant current applications. Compare against through-hole variants like JAN1N5306-1 if PCB space allows. Verify that the 100 V breakdown voltage and 2.42 mA output current align with the circuit design requirements. Check thermal management needs given the 500 mW power rating.

Current Regulation - Diodes, Transistors Part Context

This part is part of the 1N5306 series of current regulator diodes. It shares functional characteristics with other members of the family but differs in packaging and grade. The UR-1 suffix specifically denotes the round-end surface-mount variant compliant with military reliability standards.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANTX1N5306UR-1 units from authorized manufacturers. Cross-reference with JAN1N5306UR-1 for standard military grade options. Verify pinout compatibility with DO-213AB packages before substitution.
