JANTXV1N5293-1/TR

Overview

The JANTXV1N5293-1/TR is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 axial package. It provides a regulated current of 748 µA with a maximum voltage rating of 100 V and a power dissipation capacity of 475 mW. The device operates within a junction temperature range of -65°C to +175°C and meets MIL-PRF-19500/463 military qualification standards. Supplied in tape and reel packaging, this component serves as a stable constant-current source for various electronic circuits.

Feature Summary

• Provides stable constant current regulation over a broad voltage range
• Military-grade reliability qualified per MIL-PRF-19500/463 standards
• DO-7 axial leaded package with double-plug internal bond connection

Applications

• Constant current sources for LED driving circuits
• Biasing elements for transistor amplifier stages
• Current limiting protection in sensitive electronic loads

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required military specifications and packaging formats. Confirm that the tape and reel format aligns with automated assembly equipment capabilities. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability documentation prior to procurement.

Selection Notes

Select this component when a precise microampere-level constant current is required without complex circuitry. Ensure the operating voltage remains below the 100 V maximum limit to prevent breakdown. Verify that the thermal environment supports the specified junction temperature range and that the DO-7 package fits the available board space constraints.

Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators produced by Microchip. These devices function similarly to Zener diodes but regulate current instead of voltage. The JANTXV designation indicates a specific military qualification level within this family, offering enhanced performance and reliability compared to commercial variants.

Replacement Considerations

Direct substitutes include other parts from the 1N5283-1 to 1N5314-1 series with matching current ratings. Verify pinout compatibility and package dimensions before substitution. Alternative manufacturers may offer equivalent current regulator diodes, but military qualification equivalence must be confirmed separately.
