1N5532/TR

Overview

The Microchip Technology 1N5532/TR is a single Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 12 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and utilizes a DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum Zener impedance of 90 Ohms and a reverse leakage current of 50 nA at 10.8 V. It operates within a junction temperature range of -65°C to 175°C.

Feature Summary

• Provides precise voltage regulation with a 12 V nominal breakdown voltage.
• Ensures high stability through a tight ±2% voltage tolerance specification.
• Supports robust thermal performance with an extended operating temperature range up to 175°C.

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in low-power electronic systems
• General-purpose voltage regulation in industrial equipment

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm tape-and-reel packaging requirements. Ensure that the selected variant matches the required tolerance and package type for the target application. Cross-reference part numbers carefully, as suffixes may indicate differences in manufacturing lot or environmental compliance status rather than functional changes.

Selection Notes

Select this component when a 12 V Zener diode with ±2% tolerance is required in a DO-35 axial package. Consider the 500 mW power rating and 90 Ohm impedance limits during circuit design. Verify compatibility with the system's thermal management capabilities given the wide operating temperature range. Confirm that the reverse leakage current specifications meet the noise and precision requirements of the application.

Part Context

The 1N5532 series belongs to Microchip Technology's line of standard Zener diodes, widely used in discrete semiconductor applications. These devices are manufactured under strict quality controls to ensure reliability in harsh environments. The 1N5532/TR specifically denotes the tape-and-reel version of the 1N5532C, facilitating automated assembly processes while maintaining identical electrical characteristics to the bulk-packaged counterpart.

Replacement Considerations

The 1N5532D is a parameter-equivalent alternative offering tighter ±1% tolerance. Other compatible variants include 1N5532C for bulk packaging and 1N5532D-1 for specific tolerance requirements. Verify pinout and package dimensions before substitution to ensure mechanical compatibility.
