The 1SMA4757AG with Zener Diodes SMA RoHS manufactured by Shikues is a high-performance, low-profile, bidirectional TVS diode array. It is designed to protect sensitive electronic devices such as analog and digital circuits from electrical transients and overvoltage. It has an ultra-low profile (3.3 mm) and an operational temperature range of -55°C to +150°C, making it suitable for a wide range of applications. It uses a dual-diode-per-element design of ultra-fast-acting shunt clamp that can absorb repetitive high-energy transient overvoltages. The 1SMA4757AG meets the RoHS, ISO, REACH, SYEL, UL, DNV, IEC standards and is capable of working up to 1500W peak pulse power.
