JANTXV1N5308-1

Overview

The JANTXV1N5308-1 is a silicon current regulator diode manufactured by Microchip Technology under the MIL-PRF-19500/463 specification. It provides a regulated current of 2.97 mA with a maximum limiting voltage of 2.15 V and a maximum power dissipation of 500 mW. The device supports an operating temperature range from -65°C to 175°C TJ. It utilizes a DO-204AA (DO-7) axial through-hole package, ensuring compatibility with standard military-grade circuit layouts requiring stable current regulation over broad voltage ranges.

Feature Summary

• Provides constant current regulation across a wide voltage span, functioning as a counterpart to Zener diodes which regulate voltage.
• Features high source impedance for effective current stability in varying load conditions.
• Constructed with a double-plug internal bond connection within the DO-7 package to support its unique current-limiting function.

Applications

• Military electronic systems requiring qualified semiconductor components.
• Circuits needing precise current limiting or biasing where voltage variations occur.
• Replacement for commercial Zener diodes in applications requiring constant current rather than constant voltage.

Procurement Notes

Verify that the specific order suffix matches the required qualification level, as JANTXV denotes a specific military grade under MIL-PRF-19500/463. Confirm the package type is DO-7 axial leaded. Ensure the supplier provides documentation tracing back to the manufacturer's official datasheet for the 1N5283-1 through 1N5314-1 series to validate performance parameters.

Selection Notes

Select this component when a fixed current of approximately 2.97 mA is required within a 500 mW power budget. The DO-7 package is suitable for through-hole mounting. Consider the JANTXV level for enhanced reliability compared to lower grades like JAN. Ensure the application voltage does not exceed the 100 V maximum rating while maintaining the necessary voltage drop for regulation.

Part Context

This part belongs to the popular 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices are available in standard 10% tolerances and cover a current selection from 0.22 mA to 4.7 mA. The series is designed to offer a robust alternative to voltage-regulating Zeners in similar axial-leaded packages for defense and aerospace applications.

Replacement Considerations

Compatible substitutes include other parts within the 1N5283-1 through 1N5314-1 series that match the 2.97 mA current rating. Equivalent military-grade current regulator diodes from other manufacturers qualified to MIL-PRF-19500/463 may be used if pinout and electrical specifications align.
