At lower gate voltages the Rds(on) increases — the 5 V gate threshold (max) means 10 V drive is recommended for fully enhanced operation."},{"question":"What is the STF5N95K5 gate threshold voltage?","answer":"The maximum gate threshold voltage (Vgs(th)) is 5 V at 100 µA drain current. Typical threshold is lower, but the 5 V max sets the worst-case turn-on point for bias design."},{"question":"Is STF5N95K5 RoHS compliant?","answer":"The part is listed with a Tube packaging and is part of ST's standard product line. RoHS compliance is typical for current ST MOSFETs, but confirm the specific date/lot code compliance certificate with your order."},{"question":"What is the STF5N95K5 equivalent or substitute?","answer":"STMicroelectronics does not list a direct pin-compatible substitute in the same series. For a functional equivalent at 950 V and similar Rds(on), evaluate the STF5N95K3 or STF5N95K4 from the same SuperMESH5 family — verify pinout and thermal performance in your layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STF5N95K5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STF5N95K5 when reusing this data.
