The 13.4 nC total gate charge at 10 V is low enough that many PWM controllers with 1 A peak drive capability can switch this FET at 65–100 kHz without an external driver stage. Input capacitance Ciss is 360 pF at 100 V Vds, which keeps the switching node capacitance manageable and reduces the turn-on energy loss in hard-switched topologies.","metaTitle":"STD7N80K5 N-Channel 800V 6A MOSFET, SuperMESH5™, DPAK","metaDescription":"STD7N80K5 N-channel MOSFET from STMicroelectronics SuperMESH5™ series: 800V Vdss, 6A Id, 1.2Ohm Rds(on), 13.4nC Qg.

This is the voltage at which the FET just begins to conduct — the typical threshold will be lower, but the 5 V maximum ensures the device is fully off with a 0 V gate signal across the full temperature range."},{"question":"Can I use STD7N80K5 for 800 V switching?","answer":"Yes. The drain-to-source voltage rating Vdss is 800 V, so the part is rated for 800 V blocking. In a typical offline flyback converter with a 400 V DC bus (rectified 230 VAC), the 800 V rating provides adequate margin for the reflected voltage and leakage inductance spike. For universal input (90–265 VAC) designs, the 800 V rating is conservative."},{"question":"Is STD7N80K5 RoHS compliant?","answer":"Yes, the STD7N80K5 is ROHS3 compliant, meaning it meets the EU RoHS directive including the exemption-free requirements for all ten restricted substances."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD7N80K5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD7N80K5 when reusing this data.
