1N5526D

Overview

The Microchip Technology 1N5526D is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a maximum power dissipation of 500 mW. The device exhibits a Zener impedance of 30 Ohms and maintains a reverse leakage current of 1 µA at 5.5 V. It operates within a junction temperature range of -65°C to 175°C and utilizes the DO-204AH (DO-35) axial through-hole package.

Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Capable of handling high junction temperatures up to 175°C
• Constructed in an axial leaded package for through-hole mounting

Applications

• Voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Procurement Notes

Verify the specific suffix 'D' against official Microchip documentation to confirm exact tolerance and testing criteria, as variations exist within the 1N5526 family. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability for critical electronic assemblies.

Selection Notes

Select this component when a 6.8 V regulation point is required with moderate power handling capabilities. The DO-204AH package suits standard through-hole PCB layouts. Consider the 30 Ohm impedance value for dynamic load requirements and verify that the 500 mW power rating aligns with the thermal environment of the target application.

Part Context

This part belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings and tolerance grades, typically packaged in DO-35 or DO-204AH formats. These devices are commonly utilized in discrete semiconductor designs requiring reliable voltage clamping or reference functions.

Replacement Considerations

Compatible substitutes include other 1N5526 variants such as 1N5526B or 1N5526C, provided their voltage tolerances meet the design specifications. Cross-referencing datasheets is necessary to ensure equivalent power dissipation and impedance characteristics.
