JANTXV1N5312-1/TR

Overview

The JANTXV1N5312-1/TR is a current regulator diode manufactured by Microchip Technology, designed for stable current regulation across wide voltage and temperature ranges. It features a maximum regulator current of 4.29 mA and a peak operating voltage of 100 V. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C. Qualified per MIL-PRF-19500/463, it utilizes a DO-7-2 through-hole package with double-plug construction.

Feature Summary

• Provides constant current regulation over a broad operating voltage range
• Qualified per MIL-PRF-19500/463 for military applications
• Features double-plug construction for mechanical stability

Applications

• Current limiting in sensitive electronic circuits
• Biasing elements for transistor amplifiers
• Constant current sources for LED drivers

Procurement Notes

Verify the specific suffix -1/TR against the official datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure the procurement order explicitly references MIL-PRF-19500/463 qualification requirements to guarantee compliance with the JANTXV grade specifications.

Selection Notes

Select this component when a precise 4.29 mA regulation is required within a 100 V reverse voltage limit. Consider the DO-7-2 package constraints for through-hole mounting. Evaluate thermal management needs given the 500 mW power dissipation rating at elevated temperatures up to 175°C.

Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. It serves as a counterpart to Zener diodes by regulating current rather than voltage. The series offers standard 10% tolerance options ranging from 0.22 mA to 4.7 mA.

Replacement Considerations

Compatible substitutes include JAN1N5312-1/TR or commercial equivalents like 1N5312UR-1E3/TR if military qualification is not required. Verify pinout compatibility and ensure the replacement meets the 4.29 mA current and 100 V voltage specifications.
