1N5529A/TR

Overview

The 1N5529A/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 9.1 V and a power dissipation rating of 500 mW. The device exhibits a tolerance of ±10% and operates in the DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a forward voltage drop of 1.1 V. The component is supplied in tape and reel packaging to facilitate automated assembly processes.

Feature Summary

• Provides stable voltage regulation at a nominal 9.1 V level
• Engineered with a 500 mW power dissipation capacity for reliable operation
• Constructed using silicon material within a glass DO-35 axial package

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration when sourcing. Confirm the manufacturer designation as Microchip Technology or its predecessor entities such as Actel or Microsemi, as part numbers may carry historical branding variations. Ensure the DO-204AH package type matches the intended PCB footprint requirements for proper integration.

Selection Notes

Select this component when a 9.1 V Zener voltage with 500 mW power handling is required. The ±10% tolerance suits standard regulation needs rather than high-precision applications. The axial leaded format is appropriate for through-hole mounting technologies. Verify that the 100 nA leakage current meets the circuit's standby power constraints.

Part Context

This component belongs to the family of single Zener diodes produced by Microchip Technology. It shares the standard JEDEC numbering convention with similar devices like the 1N5526A. The /TR suffix specifically denotes the reel-based packaging method used for surface mount or automated insertion equipment, distinguishing it from bulk packaged variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires consulting official Microchip replacement guides or equivalent specifications from other manufacturers.
