Description

The SPV1520 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.
