1N4693-1E3/TR

Overview

The 1N4693-1E3/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C. Packaged in the DO-204AH (DO-35) through-hole axial leaded format, it exhibits a maximum reverse leakage current of 10 µA at 5.7 V. The component is supplied in reel packaging.

Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Capable of operation across an extended industrial temperature range
• Utilizes a standard through-hole axial leaded package for board mounting

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications for signal or power lines

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm packaging configuration and compliance status. Ensure that the procurement channel sources genuine components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Cross-reference the part number with current datasheets to validate electrical parameters before integration into design specifications.

Selection Notes

Select this component when a 7.5 V regulation point is required within a through-hole design constraint. Consider the 500 mW power rating and ±5% voltage tolerance to ensure compatibility with circuit load requirements. Evaluate the DO-35 package dimensions against available board space and verify thermal management capabilities for the intended operating environment.

Part Context

This component belongs to the Microchip Technology single Zener diode family, specifically utilizing the DO-204AH (DO-35) axial leaded package. The 'E3' suffix typically indicates lead-free composition compliant with environmental standards, while '/TR' denotes tape and reel packaging for automated assembly processes.

Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements must match the 7.5 V Zener voltage, 500 mW power dissipation, and DO-35 package footprint to maintain circuit functionality without modification.
