1N5523A

Overview

The Microchip Technology 1N5523A is a single Zener diode with a nominal voltage of 16 V and a power dissipation rating of 500 mW. It features a ±5% voltage tolerance and operates within a temperature range of -65°C to +175°C. The device utilizes a DO-204AH (DO-35) axial through-hole package and exhibits a maximum Zener impedance of 16 Ohms.

Feature Summary

• Provides stable voltage regulation at a nominal 16 V level for circuit protection and reference applications.
• Supports high-temperature operation up to +175°C, suitable for demanding industrial environments.
• Constructed in a robust glass axial leaded package designed for reliable through-hole mounting.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing board layouts regarding the DO-204AH footprint and verify thermal management requirements for the 500 mW dissipation rating under actual operating conditions.

Selection Notes

Select this component when a standard 16 V regulation point is required in a through-hole assembly. Consider the ±5% tolerance and 16 Ohm impedance characteristics for precision requirements. Evaluate the axial package constraints against available PCB space and ensure the operating temperature range aligns with the system's environmental specifications.

Part Context

This part belongs to the 1N35xx series of low-power Zener diodes manufactured by Microchip Technology. The series offers various voltage options in standardized axial packages, providing a consistent platform for discrete voltage regulation needs across diverse electronic designs and industrial control applications.

Replacement Considerations

Direct substitutes include other manufacturers' 1N3523A equivalents or Microchip variants such as the 1N4110-1, provided they match the 16 V nominal voltage, 500 mW power rating, and DO-35 package dimensions.
