Overview
The SZESD7351HT1G is an ESD protection diode from onsemi, designed to protect voltage-sensitive components from electrostatic discharge (ESD) and transient voltage events. This device is particularly suited for applications where ultra-low capacitance and fast response times are critical. It is ideal for high-frequency designs, such as USB 2.0 high-speed and antenna line applications, due to its low capacitance and excellent clamping capability.
