1N4484US/TR

Single Zener Diodes Overview

The Microchip Technology 1N4484US/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 62V. It features a void-less hermetically sealed glass package and operates within a junction temperature range of -65°C to +175°C. The device dissipates up to 1.5W at 25°C ambient temperature, with a maximum dynamic impedance of 80 Ohms at the test current of 4.0 mA. It includes internal metallurgical bonds and triple-layer passivation for robust construction.

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level and RoHS compliance status. Confirm the package type corresponds to the D-5A MELF form factor. Ensure the procurement documentation references MIL-PRF-19500/406 qualification levels appropriate for the intended mission requirements.

Single Zener Diodes Selection Notes

Select this component when a 62V Zener reference is needed in a surface mount configuration. Consider the thermal resistance characteristics for power dissipation limits. Evaluate the dynamic impedance specifications against circuit sensitivity requirements. Verify compatibility with available tape and reel packaging options.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5-watt Zener diodes. These devices are designed as surface mount equivalents to popular JEDEC registered axial lead series. They provide a broad selection of voltages from 3.3 to 200 volts with standard 5% tolerance.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4484US, JANTX1N4484US, and JANTXV1N4484US. These variants share the same electrical characteristics but differ in reliability qualification levels per MIL-PRF-19500/406.
