1N5524D

Overview

The Microchip Technology 1N5524D is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tight tolerance of ±1%. The device supports a maximum power dissipation of 500 mW and operates within an extended junction temperature range of -65°C to 175°C. Key electrical characteristics include a maximum Zener impedance of 30 Ohms and a reverse leakage current of 2 µA at 3.5 V. It utilizes a DO-204AH (DO-35) axial through-hole package.

Feature Summary

• Provides precise voltage regulation with ±1% tolerance for high-accuracy reference circuits
• Supports operation in extreme thermal environments with a junction temperature range up to 175°C
• Utilizes a robust DO-204AH axial leaded package suitable for through-hole mounting

Applications

• Precision voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix designation when ordering, as packaging formats such as bulk or tape-and-reel affect handling procedures. Confirm RoHS compliance status for the specific batch, as historical data indicates variations within this product family. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the semiconductor components.

Selection Notes

Select the 1N5524D when strict voltage accuracy is required due to its ±1% tolerance compared to standard variants. Consider the 500 mW power rating for thermal management in compact designs. The wide operating temperature range makes it suitable for industrial or automotive environments where standard commercial grade parts may fail under thermal stress.

Part Context

This component belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options in the DO-204AH package. The 'D' suffix typically denotes a specific tolerance class or testing parameter set distinct from other suffixes like 'B' or 'C' found in related part numbers within the same manufacturer portfolio.

Replacement Considerations

The 1N5524D/TR is a parameter-equivalent alternative offered by Microchip Technology, differing primarily in the tape-and-reel packaging format rather than electrical performance.
