1N5314-1/TR

Overview

The Microchip Technology 1N5314-1/TR is a current regulator diode belonging to the 1N5283-1 through 1N5314-1 series. It provides a regulated current of 5.17 mA with a maximum operating voltage of 100 V and a power dissipation rating of 500 mW. The device utilizes a DO-7 axial-leaded package for through-hole mounting. This component regulates current over a broad voltage range, functioning as a counterpart to Zener diodes which regulate voltage over a broad current range.

Feature Summary

• Provides stable current regulation across a wide voltage range
• Features high source impedance characteristics
• Utilizes double-plug internal bond connection in DO-7 packaging

Applications

• Current limiting circuits
• Constant current sources
• Biasing elements for active components

Procurement Notes

Verify the specific suffix against official datasheets to confirm tape-and-reel packaging versus bulk options. Ensure the JAN qualification level matches the required environmental standards for the target application. Cross-reference the manufacturer's latest documentation to confirm availability and any potential product change notifications affecting this part number.

Selection Notes

Select this component when a constant current sink or source is required within the 5.17 mA specification. Verify that the circuit voltage remains below the 100 V maximum limit to ensure proper regulation. Consider the thermal constraints imposed by the 500 mW power dissipation rating during operation. Compare against other series members if different current values are needed.

Part Context

This part is part of the popular 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. The series offers a selection of currents ranging from 0.22 mA to 4.7 mA in standard 10% tolerances. These devices are available in commercial versions and are qualified per MIL-PRF-19500/463 for military levels including JAN, JANTX, JANTXV, and JANS.

Replacement Considerations

Other members of the 1N5283-1 through 1N5314-1 series may serve as substitutes if different current ratings are acceptable. Commercial equivalents without military qualification may be used if environmental requirements allow. Verify pinout compatibility and package dimensions before substitution.
