JANTX1N3038CUR-1/TR

Single Zener Diodes Overview

The JANTX1N3038CUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for surface mount applications. It features a nominal Zener voltage of 56 V with a tight tolerance of ±2%. The device operates at a test current of 4.5 mA and exhibits a maximum reverse leakage current of 10 µA. It has a power dissipation rating of 1 W and a Zener impedance of 110 Ohms. The component is housed in a DO-213AB (MELF) package with an isolated case connection, suitable for high-reliability environments.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 56 V nominal breakdown voltage and ±2% tolerance.
• Engineered for surface mount integration using the compact DO-213AB MELF form factor.
• Features an isolated case connection to facilitate thermal management and electrical isolation.

Single Zener Diodes Applications

• Precision voltage reference circuits requiring stable 56 V levels
• Overvoltage protection stages in sensitive electronic systems
• High-reliability aerospace or military-grade power supply designs

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging if reel handling is required, as bulk variants exist within the same part family. Confirm RoHS compliance status directly with the manufacturer, as historical data suggests non-compliance for certain JANTX series iterations. Ensure the isolated case configuration meets your board layout requirements for thermal dissipation and electrical isolation.

Single Zener Diodes Selection Notes

Select this component when a stable 56 V reference is needed in a surface-mount footprint. The ±2% tolerance offers higher precision than standard commercial Zeners. Consider the 1 W power rating for thermal design. The DO-213AB package allows for automated placement. Verify that the 110 Ohm impedance is acceptable for your dynamic load requirements.

Single Zener Diodes Part Context

This part belongs to the JANTX series of Zener diodes from Microchip, which are typically characterized for enhanced reliability compared to commercial grades. The DO-213AB package is a standard metal-glass MELF format often used in ruggedized electronics. The 'CUR' designation usually implies specific testing or screening criteria defined by the manufacturer for this variant.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 56 V, 1 W Zener diodes in DO-213AB packages with ±2% tolerance, such as those from Vishay or Nexperia. Ensure the replacement maintains the isolated case connection if thermal isolation is critical. Verify that the replacement's Zener impedance and leakage current specifications meet or exceed the original requirements.
