1N5532D/TR

Overview

The Microchip Technology 1N5532D/TR is a single Zener diode with a nominal voltage of 12 V and a maximum power dissipation of 500 mW. It features a tolerance of ±1% and operates within a temperature range of -65°C to 175°C (TJ). The device has a maximum 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 tight manufacturing tolerances
• Capable of operation in extreme thermal environments up to 175°C junction temperature
• Designed for reliable performance in standard through-hole mounting configurations

Applications

• Voltage reference circuits requiring stable 12 V levels
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates tape-and-reel packaging rather than bulk supply. Confirm that the required tolerance aligns with the D variant specifications. Ensure compatibility with existing assembly processes for axial leaded components. Check for any recent product change notices regarding labeling or assembly sites before finalizing procurement plans.

Selection Notes

Select this component when a 12 V Zener diode with high precision is required for through-hole designs. The wide operating temperature range makes it suitable for industrial applications. Consider the 500 mW power rating to ensure adequate thermal management in the final circuit layout. Verify that the axial package fits the available board space constraints.

Part Context

This part belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. It shares similar electrical characteristics with other variants in the series but differs in tolerance and packaging options. The series is commonly used in general-purpose voltage regulation tasks across various electronic industries.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 1N5532D-1/TR and 1N5532C/TR from Microchip Technology. These alternatives offer comparable electrical performance and should be evaluated for pin compatibility and mechanical fit before substitution.
