2When used as shown for Reverse Polarity Protection (RPP, see page 4), the voltage available to the circuit
being protected will be two diode drops below the power supply voltage. In other words, the supply current
will pass through two diodes.

Application example BAS4002A-RPP
Advanced Reverse Polarity Protection(RPP): due to diode orientation, circuit at the right
will be protected from damage and will also function normally in the event reverse polarity is
applied to pins 2 and 3 of the BAS4002A-RPP.
