1N5526B-1/TR

Overview

The 1N5526B-1/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device operates in the DO-35 axial through-hole package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 6.2 V, a Zener impedance of 30 Ohms, and a forward voltage of 1.1 V at 200 mA. It supports a wide operating temperature range from -65°C to +175°C junction temperature.

Feature Summary

• Provides stable voltage regulation with a nominal 6.8 V Zener breakdown voltage.
• Features low reverse leakage current for efficient operation in sensitive circuits.
• Capable of handling high thermal loads with a 500 mW power dissipation rating.
• Engineered for extended reliability across extreme industrial temperature ranges.

Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Clamping applications in signal conditioning

Procurement Notes

Verify the specific suffix configuration when ordering, as it dictates the packaging format. Confirm that the component meets all required environmental standards for the target deployment. Cross-reference the manufacturer part number against official datasheets to ensure compatibility with existing design specifications before finalizing procurement actions.

Selection Notes

Select this component when a precise 6.8 V regulation point is required within a through-hole design. The ±5% tolerance suits applications needing tighter accuracy than standard variants. Ensure the circuit can accommodate the specified 30 Ohm impedance and that the 500 mW power rating aligns with the expected thermal environment.

Part Context

This component belongs to the 1N5526 series of Zener diodes produced by Microchip Technology. It shares core electrical parameters with the non-suffixed 1N5526B but differs in packaging. The series is characterized by robust performance in harsh environments, utilizing the traditional DO-35 axial leaded form factor suitable for general-purpose electronic assemblies.

Replacement Considerations

The 1N5526B is a parameter-equivalent alternative offering identical electrical specifications in bulk packaging. For surface-mount requirements, consider the JAN1N5526DUR-1, which maintains similar voltage ratings in a different package type. Verify pinout compatibility when substituting between through-hole and SMD variants.
