1N5528D

Overview

The Microchip Technology 1N5528D is a single Zener diode designed for voltage regulation applications. It features an 8.2 V nominal Zener voltage with a ±10% tolerance, ensuring stable reference levels in circuit designs. 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 provides reliable performance for general-purpose voltage clamping and protection tasks.

Feature Summary

• Provides precise voltage regulation with an 8.2 V nominal Zener potential
• Supports high thermal operation up to 175°C junction temperature
• Utilizes robust DO-204AH axial through-hole packaging for secure mounting

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• General-purpose voltage clamping in signal processing paths

Procurement Notes

Verify the specific suffix 'D' indicates ±10% tolerance against datasheet specifications. Confirm package dimensions match DO-204AH standards before integration. Ensure operating conditions remain within the specified 500 mW power dissipation limit. Cross-reference manufacturer documentation for any recent RoHS or compliance updates prior to final procurement approval.

Selection Notes

Select this component when an 8.2 V regulation point is required with moderate tolerance accuracy. The DO-204AH package suits manual assembly or standard through-hole manufacturing processes. Evaluate thermal management requirements to ensure the 500 mW rating accommodates continuous operational loads without exceeding the 175°C junction temperature limit.

Part Context

This part belongs to the 1N5528 series of Zener diodes manufactured by Microchip Technology. The series offers various tolerance options, with the 'D' suffix specifically denoting a ±10% voltage tolerance. These diodes are widely used in industrial and commercial electronics for basic voltage regulation and protection functions.

Replacement Considerations

Equivalent parts include 1N5528B and 1N5528A from Microchip Technology, which share identical electrical characteristics but differ in voltage tolerance specifications.
