On-State Voltage Drop

The on-state voltage drop is a voltage drop typically present in a transistor. When the transistor is turned on (the voltage applied to the transistor is greater than its turn-on voltage), the transistor will produce an forward on-state voltage drop in the direction of the voltage. The on-state voltage drop is a manifestation of the energy dissipation of the electronic component itself. Normaly, the on-state voltage drop of the solid state relay should be low to lower the temperature rise of the solid state relay and improve its performance.
