9.2.2.1 IEC 61000-4-5 Surge

The TPS274C65 is designed to survive against IEC 61000-4-5 surge using external TVS clamps. The device is rated to 48 V ensuring that external TVS diodes can clamp below the rated maximum voltage of the TPS274C65. Above 48 V, the device includes VDS clamps to help shunt current and ensure that the device survives the transient pulses. Depending on the class of the output,TI recommends that the system has a SMBJ36A or SMCJ36A between VS and module GND.
