Description
The SPV1540 is a cool bypass switch with a very low forward voltage drop and ultra low reverse leakage current. The former drastically reduces the power dissipation in bypass mode and prolongs the lifetime of the device, by reducing maintenance costs and shutdown due to a device failure. The latter allows the device to work at very high temperature avoiding thermal runaway phenomenon. These are clearly key benefits for all those applications requiring low power consumption to increase the system lifetime and maximize the power transfer from harvesting source to the load. For all these reasons and the strong ESD robustness, the cool bypass switch is the significant evolution with respect to the traditional standard Schottky diode.
