1N5522/TR

Overview

The Microchip Technology 1N5522/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±1%. The component 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 includes a tape-and-reel packaging suffix.

Feature Summary

• Provides stable voltage regulation at a nominal 4.7 V potential
• Supports high-temperature operation up to 175°C junction temperature
• Available in axial through-hole DO-204AH package configuration

Applications

• Voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Procurement Notes

Verify the specific ordering suffix /TR indicates tape-and-reel packaging rather than bulk supply. Confirm availability status as restricted or limited in certain regions. Ensure the ±1% tolerance variant matches design requirements compared to standard tolerance versions.

Selection Notes

Select this part when precise 4.7 V regulation is required with tight tolerance specifications. Consider the DO-204AH package for through-hole mounting constraints. Evaluate thermal management needs given the 500 mW power rating and extended temperature range capabilities.

Part Context

This component belongs to the Microchip 1N55xx series of Zener diodes, which are widely used for voltage clamping and reference applications. The 1N5522 designation specifically identifies the 4.7 V breakdown voltage characteristic within this established product family.

Replacement Considerations

The 1N5522D is listed as a parameter equivalent substitute. Verify compatibility regarding package type and tolerance specifications before substitution.
