250/300V RF DMOS

ST’s 250/300 V RF DMOS transistors are ideal for class D and E industrial power supplies. They feature an output power up to 600 W and a gain and efficiency greater than 20 dB and 70% respectively.
An important benefit when using 250 V supply voltage is the higher optimum load impedance for the device, which means a lower current requirement and consequently reduced IR (dissipation) losses in the entire system.
