1N5527D

Overview

The Microchip Technology 1N5527D is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±1%. The device operates at a test current of 1 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 500 nA at 6.8 V, a Zener impedance of 35 Ohms, and a forward voltage of 1.1 V at 200 mA. It supports an operating junction temperature range from -65°C to +175°C.

Feature Summary

• Provides stable voltage regulation with a nominal 7.5 V output.
• Capable of handling high thermal loads with a 500 mW power dissipation rating.
• Engineered for extended operational reliability across a wide temperature spectrum.

Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications within signal processing pathways.

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 1N5527D/TR utilize tape-and-reel packaging while standard versions may come in bulk. Confirm RoHS compliance status and environmental declarations against current manufacturer documentation prior to finalizing procurement specifications to ensure alignment with project requirements.

Selection Notes

Select this component when a 7.5 V regulation point is required with moderate precision. Ensure the circuit design accommodates the specified 35 Ohm impedance and 500 nA leakage limits. Verify that the physical DO-35 axial package fits the available board space and that the thermal management strategy supports the 500 mW dissipation capability under worst-case conditions.

Part Context

This part belongs to the 1N55xx series of glass-passivated Zener diodes manufactured by Microchip Technology. These components are widely utilized in general-purpose electronics for their robust construction and consistent performance characteristics. The series offers various voltage options and tolerance grades to suit diverse regulatory needs.

Replacement Considerations

Direct substitutes include 1N5527C and 1N5527B, which share identical electrical parameters but differ in voltage tolerance specifications. Cross-reference datasheets to confirm compatibility regarding package dimensions and thermal ratings before implementing any alternative component in the design.
