Single Diodes Procurement Notes

Verify the exact Reverse Voltage rating (75V vs 100V) against the specific manufacturer datasheet revision, as sources vary. Confirm the package type is DO-35 or DO-204AH equivalent. Ensure compliance with RoHS standards if required by the application specifications.

Single Diodes Selection Notes

Select this component for low-current DC rectification tasks requiring a standard silicon junction. The 200mA current capacity suits low-power signal processing. Verify thermal management requirements are minimal due to the small package size and low power dissipation characteristics.

Single Diodes Part Context

This part belongs to the family of small signal diodes manufactured by Fairchild Semiconductor. It serves as a discrete semiconductor component for basic electronic circuitry. The DO-35 package provides a compact form factor suitable for dense PCB layouts.

Single Diodes Replacement Considerations

Equivalent parts include 1N914 and 1N4148, provided the reverse voltage ratings meet the circuit requirements. Verify that substitute components offer comparable forward current capabilities and switching speeds.
