The TPSPE0521D52RGB is an electrostatic discharge (ESD) protection device manufactured by TECH PUBLIC, with a SOD-523 package size. The device is in an RoHS-compliant package, and is designed to protect sensitive components from damaging electrostatic discharges. It serves as a low-cost, effective alternative to the more costly electrostatic discharge protectors. The device includes two ESD protection diode pairs (diodes in antiparallel configuration) that protect against both AC and DC pulsed events. It also includes a low capacitance for faster protection with lower residual voltages. The device is available in both controlled- and tight-tolerance device parameters, allowing designers to customize their requirements based on application needs. It is ideal for applications such as HDMI, USB, and Ethernet connectors.
