3 Description

The TPD4S012 is a four-channel Transient Voltage Suppressor (TVS) based Electrostatic Discharge (ESD) protection diode array for USB chargers and USB On-The-Go (OTG) interfaces.

The TPD4S012 provides IEC 61000-4-2 system level ESD Protection featuring 15 V tolerance on the V_BUS line. The device is ideal for providing circuit protection for USB charger and OTG applications due to its high-voltage tolerance at the V_BUS line and small flow-through package.

5 Pin Configurations and Functions

N.C. – Not internally connected

D+, D–, and ID pins are exact equivalent ESD clamp circuits. Any of these pins can be connected to any other D+, D–, or ID pin if it becomes easier to route the traces from the USB connector.
