The Trench Field Stop structure gives a lower on-state voltage drop and faster switching than planar or non-punch-through types — the Vce(on) is 2.3 V typical at 15 V gate drive and 40 A collector current. With a 125 nC total gate charge and switching energies of 1.5 mJ on and 2.25 mJ off at 600 V, 40 A, it is sized for hard-switching applications in the 5–20 kHz range. The junction temperature range is -55°C to 175°C, which covers military and high-reliability industrial environments — motor drives in engine bays, solar inverters in desert installs, and traction converters where the die sees repeated thermal cycling from cold start to full load. The 175°C Tj(max) gives headroom above the usual 150°C industrial limit, so the thermal design can push closer to the rated 468 W power dissipation without derating prematurely. ## Switching performance at the test condition Tested at 600 V bus, 40 A collector, 10 Ohm gate resistor, and 15 V gate drive — this is a realistic hard-switching inverter leg condition. The turn-on delay is 35 ns and turn-off delay is 140 ns at 25°C. The reverse recovery time of the internal diode is 355 ns. For a 20 kHz PWM cycle, the switching losses per pulse (1.5 mJ on, 2.25 mJ off) add up to about 75 W of switching loss at that frequency — the designer needs to budget that against the 468 W package limit and the junction temperature rise. ## Package, mounting, and compliance TO-247-3 through-hole — three leads, large tab for heatsink mounting. The package suits bolted-down power stages where vibration and thermal cycling are present; the through-hole leads handle the mechanical stress better than surface-mount in high-current layouts. ROHS3 compliant per. ## Lifecycle and sourcing posture No official second-source or pin-compatible alternate is listed in the manufacturer cross-reference data.","metaTitle":"STGW40M120DF3 IGBT, 1200 V 80 A Trench Field Stop, TO-247-3","metaDescription":"STMicroelectronics STGW40M120DF3 IGBT, 1200 V collector-emitter, 80 A continuous, 160 A pulsed, Trench Field Stop, TO-247-3, -55 to 175°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Package":"Tube","IGBT Type":"Trench Field Stop","Input Type":"Standard","Gate Charge":"125 nC","Power - Max":"468 W","Mounting Type":"Through Hole","Package / Case":"TO-247-3","Test Condition":"600V, 40A, 10Ohm, 15V","lifecycle_stage":"eol_hot","Switching Energy":"1.5mJ (on), 2.25mJ (off)","Td (on/off) @ 25°C":"35ns/140ns","Operating Temperature":"-55°C ~ 175°C (TJ)","Supplier Device Package":"TO-247-3","Vce(on) (Max) @ Vge, Ic":"2.3V @ 15V, 40A","Reverse Recovery Time (trr)":"355 ns","Current - Collector (Ic) (Max)":"80 A","Current - Collector Pulsed (Icm)":"160 A","Voltage - Collector Emitter Breakdown (Max)":"1200 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.84","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.84000","currency":"USD"},{"qty":10,"price":"$6.71600","currency":"USD"},{"qty":100,"price":"$5.59660","currency":"USD"},{"qty":500,"price":"$4.93814","currency":"USD"},{"qty":1000,"price":"$4.44433","currency":"USD"},{"qty":2000,"price":"$4.16450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/80b297bf09eb0f704413e281b7d95a79.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Vce(sat) of STGW40M120DF3?","answer":"The collector-emitter saturation voltage is 2.3 V maximum at 15 V gate drive and 40 A collector current."},{"question":"Is STGW40M120DF3 Pb-free and ROHS compliant?","answer":"Yes, it is ROHS3 compliant per the manufacturer listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STGW40M120DF3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STGW40M120DF3 when reusing this data.
