JANTX1N5292-1/TR

Current Regulation - Diodes, Transistors Overview

The JANTX1N5292-1/TR is a current regulator diode manufactured by Microchip Technology. It operates in the through-hole DO-7 (DO-204AA) axial-leaded package. The device provides a regulated current of 380 µA with a maximum limiting voltage of 1.13 V. It supports a maximum peak operating voltage of 100 V and dissipates up to 475 mW. The component functions over an extended temperature range from -55 °C to +175 °C. It utilizes silicon as the diode element material and features a single configuration.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation across a broad voltage range, serving as a counterpart to Zener diodes which regulate voltage.
• Features a double-plug internal bond connection within the larger DO-7 packaging for enhanced structural integrity.
• Utilizes a larger active die element optimized for its unique function as a current limiter.

Current Regulation - Diodes, Transistors Applications

• Biasing circuits requiring constant current sources
• LED driver applications needing stable current regulation
• Protection circuits acting as current limiters

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging when ordering. Confirm that the JANTX designation meets the required radiation hardness or quality standards for the intended application. Ensure the procurement channel provides valid traceability documentation for this military-grade qualified component series.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required instead of a voltage reference. Compare the 380 µA regulation point against circuit requirements. Verify that the 100 V peak voltage rating exceeds the maximum potential voltage drop across the device in the application. Ensure the thermal management supports the 475 mW power dissipation at the highest expected ambient temperature.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. These devices offer standard 10% tolerance options ranging from 0.22 mA to 4.7 mA. The JANTX level indicates a specific qualification tier within the MIL-PRF-19500/463 standard framework provided by Microsemi/Microchip.

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 such as the 1N5292 may be considered if military qualification is not required. Verify pinout compatibility with the DO-7 package before substitution.
