ZHCSIU8A September 2018 – December 2018 TVS2201
PRODUCTION DATA.
A typical operation for the TVS2201 would be protecting a USB Type-C VBUS input, with a nominal input voltage of 20 V and a required withstand of 22 V, shown in Figure 7. In this example, a TVS2201 is protecting the input to a TPS65982 Type-C Port Controller. Without any input protection, this input voltage will rise to hundreds of volts for multiple microseconds, and violate the absolute maximum input voltage and harm the device if a surge event is caused by lightning, coupling, hot-swap ringing, or any other fault condition. This customer is adding additional surge protection on the VBUS line because they are worried about faulty connectors causing power spikes, and in addition wants to have protection against mechanical shorts in the connector that could possibly apply –20 V to the VBUS line.
