1N5525C/TR

Overview

The Microchip Technology 1N5525C/TR is a low voltage avalanche Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a tight tolerance of ±2%. The device operates at a test current of 1 mA and exhibits a maximum dynamic impedance of 30 Ohms. It is housed in the DO-204AH (DO-35) axial through-hole package, suitable for standard PCB mounting. The component supports a wide operating temperature range from -65°C to +175°C junction temperature.

Feature Summary

• Provides stable voltage regulation using low voltage avalanche technology
• Offers tight voltage tolerance for precision reference applications
• Constructed in a glass passivated axial leaded package

Applications

• Precision voltage reference circuits
• Low voltage regulation stages
• Over-voltage protection networks

Procurement Notes

Verify the specific suffix 'C' indicates the required ±2% tolerance variant, as other suffixes like 'A' or 'B' denote different tolerances. Confirm the '/TR' designation aligns with reel packaging requirements if applicable. Cross-reference the manufacturer part number against official datasheets to ensure compatibility with existing design specifications before procurement.

Selection Notes

Select this component when a precise 6.8 V reference is needed with tighter accuracy than standard variants. Ensure the circuit design accommodates the 1 mA test current condition for optimal regulation. Verify that the DO-204AH package dimensions fit the available board space and that the thermal management supports the specified junction temperature limits during operation.

Part Context

This part belongs to the 1N55xx series of low voltage avalanche Zener diodes manufactured by Microchip Technology. The series provides various voltage options in the DO-204AH package. The 'C' suffix specifically denotes the ±2% tolerance grade, distinguishing it from wider tolerance versions within the same product family.

Replacement Considerations

Compatible substitutes include the 1N5525A/TR for ±10% tolerance or 1N5525B/TR for ±5% tolerance, provided the stricter ±2% requirement is not critical. Other manufacturers offering equivalent 6.8 V Zener diodes in DO-35 packages may be considered after verifying electrical parameter alignment.
