Overview
The JANTXV1N5314-1/TR is a silicon current regulator diode manufactured by Microchip Technology. It provides a regulated current of 4.7 mA with standard 10% tolerance. The device features a maximum limiting voltage of 2.9 V and operates within a power dissipation range of 500 mW. Qualified under MIL-PRF-19500/463, it supports an operating temperature range from -65°C to +175°C. The component utilizes a DO-7 axial leaded package for through-hole mounting.
Feature Summary
- Maintains constant current over a broad voltage range
- Features high source impedance for stable regulation
- Includes internal metallurgical bond connection
Applications
- Current limiting circuits
- Biasing elements in electronic systems
- Replacement for Zener diodes in specific current regulation roles
Procurement Notes
Verify the specific suffix /TR indicates tape and reel packaging configuration. Confirm that the JAN qualification level meets the required military standards for the intended application environment. Ensure the DO-7 package dimensions align with the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a precise 4.7 mA current source is required across varying voltage conditions. Consider the 500 mW power dissipation limit and the wide temperature capability for harsh environments. Compare against other series members like 1N5283-1 through 1N5313-1 if different current values are needed.
Part Context
This part belongs to the popular 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices serve as counterparts to Zener diodes, regulating current rather than voltage. The series offers various current options from 0.22 mA to 4.7 mA in standard tolerances.
Replacement Considerations
Compatible substitutes include other parts from the 1N5283-1 to 1N5314-1 series with matching current ratings. Surface mount equivalents such as the 1N5283UR-1 through 1N5314UR-1 series may be considered if package changes are acceptable.
