Overview
The P6SMB30AT3G is a 600 Watt Peak Power Zener Transient Voltage Suppressor (TVS) diode designed by Littelfuse Inc. This component is part of the SMB series, which is engineered to protect voltage-sensitive components from high voltage, high energy transients. Although the P6SMB30AT3G has been marked for End of Life (EOL) as of December 31, 2017, and is not recommended for new designs, it remains a significant component in existing systems. The SMB series is known for its excellent clamping capability, high surge capability, low zener impedance, and fast response time, typically below 1 ns.
