Input capacitance Ciss is 1000 pF at 25 V drain-source, which influences the switching speed and the driver's peak current requirement. The threshold voltage range is specified with a 5 V maximum at 50 µA drain current. ## Temperature range and power dissipation","metaTitle":"STP12NM50 N-Channel MOSFET, 500V 12A TO-220, MDmesh","metaDescription":"STP12NM50 N-channel 500V 12A MOSFET in TO-220.
