The SS34 is an SMB (DO-214AA) GaAs Schottky Barrier Diode (SBD) RoHS manufactured by Semtech. It is designed for general high-speed switching applications, and is in a small, compact 4-pin package. The SS34 features an ultrabright ultra-low forward voltage of 0.4V and a maximum reverse voltage of 30V for reliable operation in a wide range of circuits. It also has an operating temperature range of -55°C to +150°C and a storage temperature range of -55°C to +150°C. The SS34 offers a wide variety of features, such as high maximum forward current of 3.0A, maximum peak repetitive reverse voltage of 30V, and low capacitance and low dI/dt. In addition, it is compatible with RoHS compliant, lead-free solder processing.
