The SMB series is designed to protect voltage sensitive components from high voltage, high energy transients
The document describes the 1SMB5.0AT3 Series, which are 600 Watt Peak Power Zener Transient Voltage Suppressors designed to protect voltage-sensitive components from high voltage transients. These devices feature excellent clamping capability, high surge capability, and a response time typically less than 1.0 ns. They are supplied in ON Semiconductor's Surmetic package and are suitable for communication systems, automotive, and industrial applications.
The datasheet provides comprehensive technical data including maximum ratings, electrical characteristics for various breakdown voltages ranging from 5.0V to 170V, and pulse rating curves. It also includes application notes on response time, duty cycle derating, and UL recognition for isolated loop circuit protection.
