1N5522A/TR

Overview

The Microchip Technology 1N5522A/TR is a single Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±10%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. It utilizes the DO-204AH (DO-35) axial through-hole package and is supplied in tape-and-reel packaging.

Feature Summary

• Provides stable voltage regulation with a nominal 4.7 V Zener breakdown voltage.
• Capable of handling up to 500 mW of power dissipation for robust performance.
• Engineered for extended operational reliability across a wide temperature range from -65°C to +175°C.

Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection

Procurement Notes

Verify the specific suffix designation, as the 'TR' indicates tape-and-reel packaging which differs from bulk options. Confirm RoHS compliance status directly with the manufacturer, as historical data for similar series may vary. Ensure the supplier provides official documentation matching the Microchip Technology part number to guarantee authenticity and correct electrical specifications.

Selection Notes

Select this component when a 4.7 V reference with ±10% tolerance is required in an axial leaded package. Consider the 500 mW power rating against expected circuit loads. Verify that the operating environment stays within the specified -65°C to +175°C junction temperature limits. Compare against other variants like the 1N5522A if bulk packaging is preferred over reel supply.

Part Context

This component belongs to the Microchip Technology 1N55xx series of Zener diodes, which are widely used for general-purpose voltage regulation. The series offers various voltage ratings in the DO-35 package. The 1N5522A/TR specifically denotes the 4.7 V variant supplied in tape-and-reel format for automated assembly processes.

Replacement Considerations

The 1N5522D is a parameter-equivalent alternative offering tighter ±1% tolerance. Other compatible parts include the 1N5522A for bulk packaging or equivalents from manufacturers such as onsemi and Central Semiconductor Corp, provided they match the 4.7 V, 500 mW, and DO-35 specifications.
