JANTX1N5535DUR-1

Single Zener Diodes Overview

The JANTX1N5535DUR-1 is a single silicon unidirectional voltage regulator diode manufactured by Microchip Technology. It features a nominal Zener voltage of 3.3 V and operates with a maximum power dissipation of 0.5 W. The component utilizes the DO-213AA surface-mount package, also known as MELF, with dimensions of approximately 1.7 mm in diameter and 3.7 mm in length. Designed for robust performance, it supports an operating temperature range from -65°C to +175°C. The device exhibits low reverse leakage current and maintains stable regulation characteristics suitable for demanding environments.

Single Zener Diodes Procurement Notes

Verify that the specific JANTX suffix corresponds to the required military quality level and screening standards for your application. Confirm the DO-213AA package orientation and polarity markings match your PCB footprint design. Ensure compliance with RoHS exemptions if applicable to your project constraints. Cross-reference the manufacturer's latest datasheet for any updates on mechanical drawings or testing procedures before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V regulation point is required within a compact surface-mount form factor. The JANTX designation indicates enhanced reliability specifications compared to standard commercial grades. Consider the 0.5 W power rating to ensure adequate thermal management in the final assembly. Verify that the wide temperature range meets the environmental conditions of the intended deployment scenario.

Single Zener Diodes Part Context

This part belongs to the 1N553x series of Zener diodes produced by Microchip Technology under its Microsemi division. The series offers various voltage options within the same physical package family. The JANTX variant specifically targets defense and aerospace markets requiring stringent qualification standards. It serves as a specialized alternative to through-hole equivalents in modern miniaturized designs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX1N5535 variants with different tape-and-reel packaging such as JANTX1N5535BUR-1. Commercial grade equivalents like 1N5535 may be considered if military specifications are not mandatory. Verify pinout compatibility and thermal resistance values when substituting with similar MELF packages.
