Based on the datasheet’s “Typical Applications” section (usually page 2 or 3), the Ftd02p excels in three main areas:
For low-power DC devices (12V to 48V, <1A), the Ftd02p acts as a blocking diode. Ftd02p Datasheet
Circuit: Place the diode in series with the positive power input line. If the user reverses the battery terminals, the Ftd02p blocks current flow, saving the downstream circuitry. The 1V forward drop is a reasonable penalty for safety. the Ftd02p blocks current flow
