Total gate charge is 26 nC, measured under the test condition 300 V, 10 A, 1 kOhm gate resistor, 5 V gate drive. The 1.1 µs turn-on and 4.6 µs turn-off delay times at 25 °C mean the gate driver sees moderate capacitive load — a standard automotive gate-driver IC with 2 A peak output handles the switching without external booster stages. ## On-state voltage and saturation margin Vce(on) max is 1.25 V at 4 V gate drive, 6 A collector current. That 1.25 V saturation voltage at a 6 A test point is the conduction loss floor per die; at full 25 A the Vce(on) rises with temperature, so the 125 W package power limit sets the real-world duty-cycle ceiling in a 85 °C ambient environment. ## Pulsed current and SOA boundary Pulsed collector current rating is 50 A — double the continuous 25 A — for short-duration events such as inrush or load dump. The 435 V breakdown gives enough headroom for a nominal 400 V DC bus with the usual 20 % margin for switching overshoot. The automotive qualification (AEC-Q101) means PPAP documentation is available through the manufacturer channel.","metaTitle":"STGD25N40LZAG Automotive IGBT, 435V 25A, AEC-Q101, DPAK","metaDescription":"STMicroelectronics STGD25N40LZAG automotive IGBT, 435 V collector-emitter breakdown, 25 A continuous, 26 nC gate charge, AEC-Q101 qualified, -55 to 175°C, DPAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"Logic","Gate Charge":"26 nC","Power - Max":"125 W","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Test Condition":"300V, 10A, 1kOhm, 5V","lifecycle_stage":"eol_hot","Td (on/off) @ 25°C":"1.1µs/4.6µs","Operating Temperature":"-55°C ~ 175°C (TJ)","Supplier Device Package":"D-PAK (TO-252)","Vce(on) (Max) @ Vge, Ic":"1.25V @ 4V, 6A","Current - Collector (Ic) (Max)":"25 A","Current - Collector Pulsed (Icm)":"50 A","Voltage - Collector Emitter Breakdown (Max)":"435 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.98","priceTiers":[{"qty":1,"price":"$1.98000","currency":"USD"},{"qty":10,"price":"$1.64700","currency":"USD"},{"qty":100,"price":"$1.31070","currency":"USD"},{"qty":500,"price":"$1.10906","currency":"USD"},{"qty":1000,"price":"$0.94102","currency":"USD"},{"qty":2500,"price":"$0.89397","currency":"USD"},{"qty":5000,"price":"$0.86036","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9f20369fa176e322e16616c121546e28.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STGD25N40LZAG/alternatives.json"},"ai":{"faq":[{"question":"What is the gate charge of STGD25N40LZAG?","answer":"Total gate charge is 26 nC, specified under the test condition 300 V, 10 A, 1 kOhm gate resistor, 5 V gate drive.
