1N5524C

Overview

The Microchip Technology 1N5524C is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tolerance of ±2%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 2 µA at 3 V, a Zener impedance of 30 Ohms, and a forward voltage of 1.1 V at 200 mA. It is housed in the DO-204AH (DO-35) axial through-hole package.

Feature Summary

• Provides stable voltage regulation with tight ±2% voltage tolerance
• Capable of operation across an extended industrial temperature range up to 175°C
• Utilizes a standard axial through-hole package for reliable mounting

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• General-purpose voltage regulation in industrial control equipment

Procurement Notes

Verify the specific suffix 'C' indicates the required ±2% tolerance variant, as other suffixes like 'D' offer different tolerances. Confirm the package type matches your PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your system's thermal constraints.

Selection Notes

Select this component when a 5.6 V reference with high precision is needed. The ±2% tolerance makes it suitable for applications demanding tighter accuracy than standard variants. Consider the 500 mW power rating to ensure adequate thermal headroom. The wide temperature range supports deployment in harsh environments where standard commercial parts may fail.

Part Context

This part belongs to the Microchip 1N55xx series of glass-passivated Zener diodes. These components are widely used in discrete semiconductor designs for their reliability and consistent performance. The series offers various voltage options and tolerance grades to suit diverse circuit requirements.

Replacement Considerations

The 1N5524D is a parameter-equivalent alternative offering ±1% tolerance. Verify that the tighter tolerance does not impact cost or availability negatively. Ensure the replacement maintains the same DO-204AH package and power dissipation capabilities.
