JANTXV1N5297-1

Current Regulation - Diodes, Transistors Overview

The JANTXV1N5297-1 is a current regulator diode manufactured by Microchip Technology, qualified to the MIL-PRF-19500/463 specification under the JANTXV reliability level. It belongs to the 1N5283-1 through 1N5314-1 series of 0.5-watt current regulators. The device provides a regulated current of 1.1 mA with standard 10% tolerance and operates over a broad voltage range up to a maximum anode-cathic voltage of 100 V. It dissipates a maximum power of 475 mW and functions within a temperature range of -55°C to +175°C. The component utilizes a DO-7 (DO-204AA) axial-leaded package designed for through-hole mounting.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation across a wide operating voltage range, serving as a functional counterpart to Zener diodes which regulate voltage.
• Features a double-plug internal bond connection within the DO-7 packaging to support its unique function as a current limiter.
• Qualified to military standards including JAN, JANTX, JANTXV, and JANS levels for high-reliability applications.

Current Regulation - Diodes, Transistors Applications

• Constant current sources for biasing semiconductor devices such as LEDs or laser diodes.
• Current limiting protection in sensitive electronic circuits.
• Reference current generation in analog signal processing systems.

Current Regulation - Diodes, Transistors Procurement Notes

Verify that the ordering suffix matches the required qualification level, specifically JANTXV for enhanced reliability beyond standard JAN grades. Confirm the package type is DO-7 axial leaded and ensure the manufacturer documentation aligns with MIL-PRF-19500/463 requirements. Cross-reference the specific part number against official Microchip databases to confirm availability and authenticity before procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required independent of supply voltage fluctuations within the specified breakdown region. Compare the 1.1 mA output against other series members like 1N5296-1 or 1N5298-1 if different current values are needed. Ensure the circuit design accommodates the minimum operating voltage required to maintain regulation and the maximum voltage rating of 100 V.

Current Regulation - Diodes, Transistors Part Context

This device is part of the broader 1N5283-1 through 1N5314-1 family of current regulator diodes offered by Microchip. These components share similar physical characteristics and operational principles but differ in their specific regulated current outputs ranging from 0.22 mA to 4.7 mA. The JANTXV designation indicates a higher quality control and testing standard compared to commercial or basic military JAN versions.

Current Regulation - Diodes, Transistors Replacement Considerations

Compatible substitutes include JANTX1N5297-1 and JAN1N5297-1, provided the lower reliability grades meet the application requirements. Other manufacturers producing MIL-PRF-19500/463 qualified parts may offer equivalent functionality, though pinout and mechanical dimensions must be verified for direct replacement.
