S1F79100Y Series
R1 helps reduce the affect of ISS on VF. It is also required when ISS is lower than the diode bias current. For certain input voltages, a Zener diode with the reverse polarity can be used.
High Input Voltages
A preliminary regulator circuit is required to bring the input voltage within the S1F79100Y series rated range.
