4-channel USB ESD solution with power clamp



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 VBUS line. The device is ideal for providing circuit protection for USB charger and OTG applications due to its high-voltage tolerance at the VBUS line and small flow-through package.
