1N5532D

Overview

The Microchip Technology 1N5532D is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 12 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 from -65°C to +175°C. Key electrical characteristics include a maximum Zener impedance of 90 Ohms and a reverse leakage current of 50 nA at 10.8 V. It utilizes a DO-204AH (DO-35) axial through-hole package.

Feature Summary

• Provides precise voltage regulation with a nominal 12 V breakdown voltage.
• Ensures high stability through a tight ±1% voltage tolerance specification.
• Supports operation in extreme environments with a junction temperature range up to 175°C.
• Features low reverse leakage current for efficient performance in sensitive circuits.

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Voltage regulator designs

Procurement Notes

Verify the specific suffix designation against official datasheets, as variations such as tape-and-reel options may exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as environmental declarations can vary by production batch. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a stable 12 V reference is required with strict tolerance limits. The wide operating temperature range makes it suitable for industrial or automotive environments where thermal stability is critical. Consider the DO-35 package constraints regarding board space and mounting orientation during the design phase.

Part Context

This part belongs to the standard 1N55xx series of Zener diodes manufactured by Microchip Technology. These components are widely used in discrete semiconductor applications requiring reliable voltage clamping. The 1N5532D specifically targets applications needing higher precision than standard commercial grades offer.

Replacement Considerations

Official parameter-equivalent substitutes include 1N5532D-1 and 1N5532D/TR from Microchip Technology. Verify that any alternative maintains the same 12 V nominal voltage, ±1% tolerance, and 500 mW power rating to ensure circuit compatibility.
