Current Regulation - Diodes, Transistors Applications

• Constant current sources for LED driving
• Biasing circuits for transistors and active components
• Current limiting protection in sensitive electronic systems

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration against the official datasheet. Confirm MIL-PRF-19500/463 qualification status is required for the intended application. Ensure the DO-7 package dimensions match the PCB footprint design constraints before finalizing procurement orders.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source near 517 µA is required with high voltage tolerance. Compare against commercial equivalents if military qualification is not mandatory. Consider thermal management requirements due to the 500 mW power rating and ensure the operating voltage remains below the 100 V peak limit during transient conditions.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN1N5283-1 through JAN1N5314-1 series of 0.5 watt current regulators. These devices serve as counterparts to Zener diodes by regulating current over a broad voltage range rather than voltage over a broad current range. The series offers various current values from 0.22 mA to 4.7 mA in standard tolerances.

Current Regulation - Diodes, Transistors Replacement Considerations

Parametric equivalents include JAN1N5290-1 without the reel suffix or other current regulator diodes with similar 517 µA ratings. Verify package compatibility and electrical parameters such as dynamic impedance and leakage current before substitution.
