1N4693

Overview

The Microchip Technology 1N4693 is a Zener voltage regulator diode designed for precision voltage reference and regulation applications. It features a nominal Zener voltage of 7.5 V with a tight tolerance of 5%. The device operates in the DO-213AA-2 surface-mount package, offering a power dissipation rating of 500 mW. Key electrical characteristics include a maximum reverse leakage current of 10 uA and a test current of 50 uA. It supports a wide operating temperature range from -65 C to +175 C, ensuring reliability in demanding environments.

Feature Summary

• Provides stable voltage regulation with a 7.5 V nominal Zener voltage.
• High thermal stability with an extended operating temperature range up to 175 C.
• Low leakage current ensures minimal power loss in high-impedance circuits.
• Compact surface-mount packaging facilitates automated assembly.

Applications

• Precision voltage reference circuits
• Over-voltage protection systems
• Power supply regulation modules

Procurement Notes

Verify the specific suffix (e.g., TR) for reel packaging requirements against official datasheets. Confirm RoHS compliance status as indicated in manufacturer documentation. Ensure the DO-213AA-2 footprint matches PCB design constraints. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 7.5 V reference is required in a compact SMD form factor. Consider the 5% tolerance for general regulation tasks. Evaluate the 500 mW power dissipation limit against circuit load conditions. Verify compatibility with high-temperature operational environments due to the 175 C maximum rating.

Part Context

The 1N4693 belongs to the standard Zener diode family manufactured by Microchip Technology. It shares functional similarities with other 1N46xx series devices but is distinguished by its specific 7.5 V breakdown voltage. The device is part of Microchip's broader portfolio of discrete semiconductor solutions for industrial and commercial electronics.

Replacement Considerations

Direct substitutes include equivalent 7.5 V Zener diodes in DO-213AA-2 packages from other manufacturers. Verify pinout compatibility and thermal characteristics before substitution. Alternative part numbers within the same series may offer different tolerances or packaging options.
