Overview
The TPD4E004DRYR is a low-capacitance transient voltage suppression (TVS) device manufactured by Texas Instruments. This quad-channel TVS diode array is designed to protect sensitive electronics attached to communication lines from electrostatic discharge (ESD) events. Each of the four channels consists of a pair of diodes that steer ESD current pulses to VCC or GND, ensuring the protection of high-speed data interfaces.
