9.2.1.6 Transient Suppressor

Voltage transients on the TPS2376-H can be caused by connecting or disconnecting the PD, or by other environmental conditions like ESD. A transient voltage suppressor, such as the SMAJ58A, should be installed after the bridge and across the TPS2376-H input as shown in Figure 13.

Some form of protection may be required from V_(VDD-RTN) if adequate capacitance is not present. RTN is a high impedance node when the MOSFET is off. Some topologies may cause large transients to occur on this pin when the PD is plugged into an active supply.
