Introduction to General-Purpose Products for Digital Cameras

Introduction to Key Devices

About Diode Products

ESD measures are becoming an issue of great importance in the area of digital cameras, where products are shrinking and offering more sophisticated functions. The NSDA series, our ESD protective device series, is suitable for use in USB 2.0 and IEEE 1394 compliant high-speed interfaces, and its low terminal capacitance allows ESD protection that does not affect high-speed data transfer. A choice of two- or four-circuit product packages is available depending on the number of data lines.
