JANTX1N5304-1/TR

Current Regulation - Diodes, Transistors Overview

The JANTX1N5304-1/TR is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 (DO-204AA) axial package. It provides a regulated current of 1.98 mA with a maximum peak operating voltage of 100 V and a maximum limit voltage of 1.75 V. The device dissipates up to 475 mW and operates within a temperature range of -55°C to +175°C. Qualified under MIL-PRF-19500/463, it features a minimum dynamic impedance of 420 uohms and is supplied in a reel.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation over a broad voltage range
• Qualified for military standards including JAN, JANTX, JANTXV, and JANS levels
• Utilizes double-plug internal bond connection for unique current limiting function

Current Regulation - Diodes, Transistors Applications

• Constant current sources for LED biasing
• Current limiting protection in sensitive circuits
• Biasing elements for transistor amplifiers

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging rather than bulk when ordering. Confirm the JANTX qualification level meets project requirements against the broader MIL-PRF-19500/463 series. Ensure the DO-7 through-hole form factor aligns with the target PCB layout constraints before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise 1.98 mA regulation is required within a 100 V compliance window. Compare against the standard 1N5304 commercial version if military-grade reliability is not necessary. Consider the 475 mW power dissipation limit to ensure adequate thermal management in the final assembly design.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the popular 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices offer a selection from 0.22 mA to 4.7 mA in standard 10% tolerances. They serve as counterparts to Zener diodes by regulating current over a broad voltage range instead of voltage over a broad current range.

Current Regulation - Diodes, Transistors FAQ

What is the difference between the JANTX and JANTXV qualification levels?

Both are qualified under MIL-PRF-19500/463. JANTX represents a higher reliability level than JAN, while JANTXV offers even stricter screening and testing criteria for enhanced performance consistency.

How does the DO-7 package differ from standard axial packages?

The DO-7 packaging option offers a double-plug internal bond connection with a larger active die element, providing a unique function as a current limiter compared to standard configurations.
