The following design feature should be observed: In applications having a power supply specified such that VDS
has large transient surge voltages, a clamp snubber circuit of a capacitor-resistor-diode (CRD) combination
should be added on the primary winding, P, or a damper snubber circuit of a capacitor (C) or a resistor-capacitor
(CR) combination should be added between the D/ST pins and the S/OCP pin.
