Additional Details

The RCLAMP0504F utilizes Semtech's proprietary EPD (Enhanced Protection Diode) technology to achieve superior protection performance. It's a four-channel device, meaning it can protect four separate I/O lines. The device operates over a temperature range of -40°C to +125°C. Its low leakage current ensures minimal impact on system power consumption. The clamping voltage is typically around 7V at a surge current of 1A. The device is provided in tape and reel packaging for automated assembly.
