High Power Dual Schottky Rectifiers STF30120C and STF30120CR with High Reverse Voltage Capability of 120V
The STF30120C and STF30120CR are 30A (total package), 120V Schottky Rectifiers packaged in the ITO-220AB fully isolated package. The STF30120C is Schottky pair in the common cathode configuration. The STF30120CR is a Schottky pair in the common anode configuration. Both devices have a very low forward voltage, VF, drop, and low reverse leakage current, IR, resulting in low total conduction losses and enhanced levels of efficiency. The common cathode and common anode configurations facilitate circuit and PC board design in common applications such as output rectification. The high reverse voltage capability and low total conduction losses of the devices make them ideal solutions for high-frequency, energy-sensitive applications such as Solid State Lighting (SSL), alternative energy inverters, or output bridge rectifiers in switching power supplies (SMPS or DC/DC). The devices employ guard ring construction for enhanced levels of reliability and robust reverse energy capability.
