1N5522C/TR

Overview

The Microchip Technology 1N5522C/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and utilizes the DO-204AH (DO-35) axial through-hole package. It operates within a junction temperature range of -65°C to +175°C, ensuring reliability in demanding environments.

Feature Summary

• Provides precise voltage regulation with a 4.7 V nominal Zener voltage and ±2% tolerance.
• Supports high-temperature operation with a junction temperature range extending up to +175°C.
• Utilizes a standard DO-204AH (DO-35) axial leaded package for reliable through-hole mounting.

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix configuration when ordering, as the /TR designation indicates tape and reel packaging which may differ from bulk variants. Confirm availability status directly with authorized distributors, as supply levels for this component can fluctuate. Ensure the procurement channel provides valid traceability documentation consistent with Microchip Technology standards.

Selection Notes

Select the 1N5522C/TR variant specifically when a 4.7 V Zener voltage with ±2% tolerance is required. This part is suitable for designs needing higher precision than standard ±5% or ±10% versions. Consider the 500 mW power rating and DO-35 package constraints during thermal and mechanical layout planning.

Part Context

This component belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options and tolerance grades, typically housed in the DO-204AH (DO-35) axial package. These diodes are widely used in general-purpose discrete semiconductor applications requiring reliable voltage regulation.

Replacement Considerations

The 1N5522C is a parameter-equivalent alternative without the tape and reel packaging. Other variants such as 1N5522A (±10%) or 1N5522D (±1%) offer different tolerances but share the same electrical characteristics and package type.
