JANTXV1N4124UR-1/TR

Single Zener Diodes Overview

The JANTXV1N4124UR-1/TR is a silicon Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA package. It features an isolated case connection and operates within a temperature range of -65°C to 175°C. Key electrical specifications include a nominal Zener voltage of 43 V with a maximum impedance of 250 Ohms. The device supports a power dissipation of 500 mW and maintains a tolerance of ±5%.

Single Zener Diodes Feature Summary

• Utilizes an isolated case connection for enhanced thermal and electrical management
• Engineered for high-temperature reliability with operation up to 175°C
• Designed for surface-mount integration using the DO-213AA form factor

Single Zener Diodes Applications

• Voltage regulation in aerospace electronic systems
• Over-voltage protection circuits in military-grade hardware
• Reference voltage generation in radiation-hardened designs

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging rather than bulk supply. Confirm RoHS compliance status as non-RoHS variants may exist within this product line. Ensure the isolated case requirement matches the system design constraints before finalizing the order.

Single Zener Diodes Selection Notes

Select this component when a stable 43 V reference is required in space-constrained surface-mount layouts. The DO-213AA package offers a compact footprint suitable for automated assembly processes. Consider the 500 mW power rating to ensure adequate thermal headroom under continuous operating conditions.

Single Zener Diodes Part Context

This part belongs to the JANTXV series of radiation-hardened discrete semiconductors produced by Microchip Technology. The series targets defense and aerospace markets requiring high reliability. The JANTXV designation signifies specific screening levels beyond standard commercial grades.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 43 V Zener voltage, 500 mW power rating, and DO-213AA package. Verify that any alternative component also provides an isolated case connection and meets the same temperature and radiation hardness requirements.
