Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.
