The Semtech ZM4754A is a Zener Diode LL-41 RoHS designed for protection of two lines from ESD, lightning, and other overvoltage transients. The device is composed of two Zener diodes connected in series, enabling suppression of transients up to 28V at 5A. The ZM4754A requires as low as 18 mA to provide overvoltage protection. It is packaged in an industry-standard, surface-mount LL-41 (2.5x5.0x4.3 mm) and is RoHS-compliant. The device can be used for over-voltage protection of a wide range of products and applications, such as cell phones, PDAs, gaming devices, telecom systems, and security cameras.
