This is the operating junction temperature, not the ambient — derating applies based on power dissipation and thermal resistance."},{"question":"Is STB45N30M5 RoHS compliant?","answer":"Yes, the STB45N30M5 is ROHS3 compliant, meaning it meets the current European Union directive on restriction of hazardous substances for lead-free soldering processes."},{"question":"Can I use STB45N30M5 in place of STB45N30M4?","answer":"The STB45N30M5 is from the same MDmesh M5 family as the STB45N30M4 and shares the same TO-263 package and 300 V rating. The key difference is Rds(on): the M5 variant offers a lower 40 mOhm maximum versus the M4's higher on-resistance. If your design relies on the M4's specific switching characteristics or gate charge, verify the M5's 95 nC Qg against your driver's capability before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STB45N30M5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STB45N30M5 when reusing this data.
