Overview

The DALC208SC6 is a low-capacitance diode array designed for high-speed data line protection and ESD suppression. It features four unidirectional channels in a rail-to-rail steering configuration, capable of protecting lines with a reverse standoff voltage of 5V. The device is optimized for signal integrity in high-frequency applications, supporting a bandwidth of up to 100MHz.

Why Choose This Part

The component offers extremely low leakage current of 1uA and a wide operating temperature range from -55C to 150C. Its SOT-23-6 package provides a compact footprint for space-constrained PCB designs while offering 100MHz bandwidth for transparent operation on data buses.

Applications
