For a new design, look at current-production 1200 V N-channel MOSFETs in a TO-220 package with similar Rds(on) and gate charge from ST's later series or from competitors such as Infineon or IXYS. For an existing BOM, we can help source the original part through the surplus channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STP6N120K3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STP6N120K3 when reusing this data.
