It features high source impedance and JEDEC registered 1N5287 designation. The component supports an operating temperature range from -65°C to +175°C junction temperature.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation over a broad voltage range
• Qualified per MIL-PRF-19500/463 for military applications
• Features high source impedance for consistent performance

Current Regulation - Diodes, Transistors Applications

• Military electronic systems requiring reliable current limiting
• Circuits needing constant current sources in axial packages
• Replacement for Zener diodes in current-regulated designs

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix '-TR' against official Microchip documentation to confirm tape-and-reel packaging, as standard datasheets often list bulk DO-7 variants. Ensure the JAN TXV grade matches project reliability requirements. Cross-reference the part number with the latest manufacturer datasheet to confirm availability and exact electrical tolerances before procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise constant current source is required within a small axial footprint. The 363 µA regulation point suits low-power signal conditioning or biasing circuits. Verify that the 100 V breakdown voltage accommodates the circuit's maximum potential difference across the diode during operation.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the popular 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. These devices offer a counter-part offering to Zener diodes, regulating current over a broad voltage range rather than voltage over a broad current range. The series is available in standard 10% tolerance options.

Current Regulation - Diodes, Transistors Replacement Considerations

Compatible substitutes include other parts from the 1N5283-1 to 1N5314-1 series with matching current ratings. Commercial equivalents may lack the MIL-PRF-19500/463 qualification. Verify pinout compatibility and thermal characteristics when substituting.
