Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as this part number was originally associated with Fairchild Semiconductor before its acquisition by onsemi. Confirm that the component meets current quality standards and traceability requirements. Ensure the ordering suffix matches the required packaging configuration for your production line.

Single Zener Diodes Selection Notes

Select this component when a precise 2.7 V reference is required in a standard DO-35 footprint. Consider the 5% tolerance and 30 Ohm impedance for circuit stability. Evaluate the high-temperature rating if the application involves significant self-heating or harsh thermal environments.

Single Zener Diodes Part Context

This device belongs to the 1N4370A through 1N4372A series of 500 mW Zener diodes. These components are widely used in general-purpose electronics for basic voltage regulation tasks. The series offers a standardized form factor compatible with through-hole mounting technologies.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N747A and 1N4371AE3. Verify pinout compatibility and ensure the replacement maintains the same 2.7 V nominal voltage and 500 mW power rating.
