AEC-Q101 qualification confirms suitability for automotive power-train and chassis-domain applications where reliability screening is mandatory. The 29 nC total gate charge keeps the gate-drive power low, a practical advantage when the IGBT is switched from a logic-level PWM controller through a bootstrap supply. ## Switching performance and thermal headroom Turn-on delay is 650 ns and turn-off delay is 13.5 µs at 25°C under a 300 V, 10 A test condition with a 5 V gate drive — the asymmetric delay reflects the Miller plateau during turn-off and must be factored into dead-time settings in half-bridge topologies. Continuous collector current is 25 A; pulsed current capability reaches 40 A, sized for inrush and short-circuit events in motor-drive and inductive-load switching. Collector-emitter saturation voltage is 1.7 V typical at 4.5 V gate drive and 10 A collector current, which sets the conduction loss floor for efficiency calculations. ROHS3 compliant; no exemption claims needed for lead-free assembly lines.","metaTitle":"STGD18N40LZT4 IGBT, 420V 25A, AEC-Q101, DPAK","metaDescription":"STMicroelectronics PowerMESH™ IGBT, 420V Vces, 25A Ic, 125W max, AEC-Q101 qualified, -55 to 175°C TJ, DPAK package.","metaKeywords":null},"attributes":{"series":"PowerMESH™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Grade":"Automotive","Series":"PowerMESH™","Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"Logic","Gate Charge":"29 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, 5V","lifecycle_stage":"eol_hot","Td (on/off) @ 25°C":"650ns/13.5µs","Operating Temperature":"-55°C ~ 175°C (TJ)","Supplier Device Package":"DPAK","Vce(on) (Max) @ Vge, Ic":"1.7V @ 4.5V, 10A","Current - Collector (Ic) (Max)":"25 A","Current - Collector Pulsed (Icm)":"40 A","Voltage - Collector Emitter Breakdown (Max)":"420 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1","priceTiers":[{"qty":1,"price":"$2.10000","currency":"USD"},{"qty":10,"price":"$1.74300","currency":"USD"},{"qty":100,"price":"$1.38710","currency":"USD"},{"qty":500,"price":"$1.17372","currency":"USD"},{"qty":1000,"price":"$0.99588","currency":"USD"},{"qty":2500,"price":"$0.94609","currency":"USD"},{"qty":5000,"price":"$0.91052","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7446174f27d5a9d9b14047c259f2da12.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STGD18N40LZT4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STGD18N40LZT4?","answer":"The STGD18N40LZT3 shares the same PowerMESH™ series and DPAK footprint, but the LZT4 variant carries AEC-Q101 automotive qualification which the LZT3 may not — confirm the grade requirement before substituting."},{"question":"Does STGD18N40LZT4 require a heatsink?","answer":"At 125 W maximum power dissipation, the DPAK package cannot dissipate that level continuously without a thermal management solution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STGD18N40LZT4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STGD18N40LZT4 when reusing this data.
