It is specified for hard-switching applications such as motor drives, PFC stages, and induction heating where the 400 V test condition (400 V, 20 A, 10 Ohm, 15 V) directly mirrors the nominal bus voltage. ## Switching energy and gate drive budget Total switching energy at the 400 V / 20 A test point is 77 µJ turn-on and 170 µJ turn-off. The off-loss dominates the thermal calculation — the designer should size the heatsink for the turn-off component, especially at higher switching frequencies. Gate charge is 120 nC at 15 V drive. A typical gate driver delivering 1 A peak can charge the gate in roughly 120 ns; the 30 ns turn-on delay and 139 ns turn-off delay (at 25 °C) are consistent with a moderate-speed IGBT suited to 10–40 kHz operation. ## -55 to 175 °C junction — full military temperature coverage","metaTitle":"STGWT20H65FB IGBT, 650V 40A Trench Field Stop, TO-3P","metaDescription":"STGWT20H65FB IGBT: 650V Vces, 40A Ic, Trench Field Stop, 120 nC gate charge, 77/170 µJ switching energy, -55 to 175°C, TO-3P.","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":"120 nC","Power - Max":"168 W","Mounting Type":"Through Hole","Package / Case":"TO-3P-3, SC-65-3","Test Condition":"400V, 20A, 10Ohm, 15V","lifecycle_stage":"eol_hot","Switching Energy":"77µJ (on), 170µJ (off)","Td (on/off) @ 25°C":"30ns/139ns","Operating Temperature":"-55°C ~ 175°C (TJ)","Supplier Device Package":"TO-3P","Vce(on) (Max) @ Vge, Ic":"2V @ 15V, 20A","Current - Collector (Ic) (Max)":"40 A","Current - Collector Pulsed (Icm)":"80 A","Voltage - Collector Emitter Breakdown (Max)":"650 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.14","priceTiers":[{"qty":1,"price":"$3.14000","currency":"USD"},{"qty":10,"price":"$2.63800","currency":"USD"},{"qty":100,"price":"$2.13380","currency":"USD"},{"qty":500,"price":"$1.89670","currency":"USD"},{"qty":1000,"price":"$1.62405","currency":"USD"},{"qty":2000,"price":"$1.52922","currency":"USD"},{"qty":5000,"price":"$1.46712","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2b8c6c26252b4bb5cd670be487cf3b16.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STGWT20H65FB/alternatives.json"},"ai":{"faq":[{"question":"What is the switching energy of the STGWT20H65FB?","answer":"At the test condition of 400 V, 20 A, 10 Ohm gate resistor, and 15 V gate drive, turn-on energy is 77 µJ and turn-off energy is 170 µJ.
