1N4693

Overview

The Motorola 1N4693 is a silicon epitaxial planar Zener diode 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 +200°C. Key electrical specifications include a maximum reverse leakage current of 10 µA at rated voltage. The component is housed in a DO-35 axial glass package, ensuring high stability and reliability for general-purpose circuit protection and reference tasks.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Constructed using silicon epitaxial planar technology for enhanced durability
• Capable of withstanding high-temperature soldering conditions up to 265°C

Applications

• Voltage regulation in low-power electronic circuits
• General-purpose voltage reference sources
• Circuit protection against overvoltage transients

Procurement Notes

Verify the specific manufacturer origin, as the 1N4693 designation is utilized by multiple suppliers including Microchip, Vishay, and EIC Semiconductor. Confirm that the received component matches the required DO-35 package style and 7.5V Zener voltage specification. Ensure documentation confirms compliance with relevant environmental standards if hermetic sealing is required for the intended application environment.

Selection Notes

Select this component when a standard 7.5V Zener reference is needed with moderate power handling capabilities. The DO-35 package offers a compact form factor suitable for through-hole mounting. Consider the ±5% voltage tolerance and 10 µA leakage current limits to ensure compatibility with sensitive downstream circuitry requirements.

Part Context

The 1N4693 belongs to the widely recognized 1N46xx series of axial leaded Zener diodes. This series provides a standardized solution for voltage clamping and regulation in consumer and industrial electronics. Motorola's implementation aligns with industry-standard electrical characteristics defined for this part number, ensuring interchangeability with other major manufacturers' equivalents.

Replacement Considerations

Equivalent parts include the 1N4693 variants from Microchip Technology, Vishay Telefunken, and EIC Semiconductor. Verify pinout compatibility and package dimensions (DO-35) before substitution. Ensure the replacement unit meets the same 7.5V nominal voltage and 500mW power dissipation ratings.
