The ESD7504 surge protection is designed to protect high speed data lines from ESD. Ultra−low capacitance and low ESD clamping voltage make this device an ideal solution for protecting voltage sensitive high speed data lines. The flow−through style package allows for easy PCB layout and matched trace lengths necessary to maintain consistent impedance between high speed differential lines such as USB 3.0.

The ESD5Zxx Series is designed to protect voltage sensitive components from ESD and transient voltage events. Excellent clamping capability, low leakage, and fast response time, make these parts ideal for ESD protection on designs where board space is at a premium. Because of its small size, it is suited for use in cellular phones, portable devices, digital cameras, power supplies and many other portable applications.

The UCLAMP3301D is constructed using proprietary  EPD process technology.  The EPD process provides low standoff voltages with  significant reduc-tions in leakage currents and capacitance over silicon-avalanche diode processes. They feature a true operating voltage of 3.3 volts for superior  protection when compared to traditional pn junction  devices. The UCLAMP3301D is in a SOD-323 package and will  protect one unidirectional line. They give the designer  the flexibility to protect one line in applications where  arrays are not practical.
