The 10 V drive voltage is the sweet spot for minimum Rds(on); driving with a lower gate voltage increases resistance and losses, so budget a 10 V gate supply or a bootstrap circuit in the gate driver stage. ## 22 nC gate charge — switching speed and drive loss A total gate charge of 22 nC at 10 V means the gate driver sees a modest capacitive load, keeping drive losses low even at higher switching frequencies. The 620 pF input capacitance at 100 V Vds confirms a relatively small Miller plateau, which helps maintain clean switching edges and reduces dead-time requirements in half-bridge configurations.","metaTitle":"STP14N80K5 N-Channel MOSFET, 800V, 12A, TO-220-3","metaDescription":"STP14N80K5 N-Channel MOSFET from STMicroelectronics MDmesh K5 series. 800V Vdss, 12A Id, 445mOhm Rds(on).
