1N5528/TR

Overview

The Microchip Technology 1N5528/TR is a single Zener diode designed for voltage regulation applications. It features an 8.2 V nominal Zener voltage with a 5% tolerance, tested at 1 mA. The device dissipates up to 500 mW and exhibits a maximum reverse leakage current of 500 nA and a Zener impedance of 40 Ohms. It operates within a temperature range of -65°C to +175°C. Packaged in the DO-204AH (DO-35) axial through-hole format, it is supplied in reel packaging.

Feature Summary

• Provides stable voltage regulation using a single Zener junction configuration.
• Capable of operation across an extended industrial temperature range up to 175°C.
• Utilizes an axial leaded package suitable for standard through-hole mounting processes.

Applications

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

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm the reel packaging configuration. Ensure that the required voltage tolerance and thermal performance align with the design specifications before procurement. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability.

Selection Notes

Select this component when a through-hole solution is required for 8.2 V regulation. Consider the 500 mW power dissipation limit and the 40 Ohm impedance characteristics during circuit design. Verify compatibility with the target operating temperature range and ensure the axial package fits the available board space constraints.

Part Context

This component belongs to the 1N5528 series of Zener diodes manufactured by Microchip Technology. It shares core electrical parameters with variants such as the 1N5528B and 1N5528A, differing primarily in packaging and tolerance specifications. The series is widely used in discrete semiconductor applications requiring reliable voltage clamping.

Replacement Considerations

The 1N5528B is documented as a parameter-equivalent alternative. Verify pinout compatibility and exact tolerance requirements when substituting.
