Input capacitance is 340 pF at 100 V drain-source. ## Temperature range and gate drive Gate threshold voltage is 5 V maximum at 100 µA drain current, so the 10 V drive recommended for minimum Rds(on) is well above the threshold — no risk of operating in the linear region at turn-on. Maximum gate-source voltage is ±30 V, giving margin against ringing on the gate node in a hard-switched topology.","metaTitle":"STD9N80K5 N-Channel MOSFET, 800 V, 7 A, MDmesh K5","metaDescription":"STD9N80K5 N-Channel MOSFET from STMicroelectronics MDmesh K5 series. 800 V Vdss, 7 A Id, 900 mOhm Rds(on).
