1N5527A/TR

Overview

The 1N5527A/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±10%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. Packaged in the DO-204AH (DO-35) axial through-hole format, it is supplied in tape and reel packaging. Key electrical characteristics include a reverse leakage current of 500 nA at 6 V and a forward voltage of 1.1 V at 200 mA.

Feature Summary

• Provides stable voltage regulation with a nominal 7.5 V Zener potential
• Supports high thermal operation up to a 175°C junction temperature
• Utilizes an axial leaded package suitable for through-hole mounting

Applications

• General purpose voltage reference circuits
• Power supply output regulation
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm packaging configuration. Ensure that the required tolerance class aligns with circuit design specifications. Confirm availability status directly with authorized distributors as stock levels fluctuate. Validate compliance requirements such as RoHS or REACH status prior to integration into final assemblies.

Selection Notes

Select this component when a standard 7.5 V reference is required in a through-hole axial package. Consider the 500 mW power rating for thermal management constraints. Evaluate the ±10% voltage tolerance against precision requirements. Compare operating temperature limits against environmental conditions to ensure reliability under specified load conditions.

Part Context

This part belongs to the 1N55xx series of Zener diodes produced by Microchip Technology. The series offers various voltage options within the DO-35 package style. These components are widely used in discrete semiconductor applications requiring reliable voltage clamping or referencing functions in electronic circuits.

Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes rated at 7.5 V and 500 mW. Verify pinout compatibility and physical dimensions before substitution. Ensure equivalent electrical parameters including leakage current and impedance are met.
