STR-A6100 Series

6. Typical Application Circuit

 The PCB traces of D pins should be as wide as possible, in order to enhance thermal dissipation.

 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 (RC) combination should be added between the D pin and

the S/OCP pin.

 As shown in Figure 6-2, STR-A6153E does not need diode connected to ST pin.
