If you need to either amplify or switch between signals in your design, then STMicroelectronics" STP4N62K3 power MOSFET is for you. Its maximum power dissipation is 70000 mW. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This MOSFET transistor has a minimum operating temperature of -55 °C and a maximum of 150 °C. This device is made with supermesh technology. This N channel MOSFET transistor operates in enhancement mode.
