The SiC technology gives this part a 690 mOhm maximum on-resistance at 6 A with a 20 V gate drive, and a junction temperature range from -55°C to 200°C — notably wider than typical Si MOSFETs, which matters for designs that must survive thermal cycling or high ambient conditions. ## Switching and drive — gate charge and capacitance Input capacitance measures 290 pF at 400 V drain-source, so the Miller plateau is narrow and the switching losses stay manageable in hard-switched topologies. ## Thermal and power dissipation — sizing the heatsink In practice, a 12 A continuous drain at 1200 V is a switching application, not linear — the conduction loss at 6 A with 690 mOhm Rds(on) is about 25 W, and the switching loss adds depending on frequency. The TO-247 package with its large tab can bolt to a heatsink or a cold plate; the junction-to-case thermal path is the limiting factor for continuous current above 6 A. The -55°C to 200°C junction range means the part can be used in engine-bay, downhole, or aerospace auxiliary power designs where ambient exceeds 125°C, as long as the case is kept within the derating curve. For a production BOM, there is no imminent LTB risk, but SiC devices are still in a supply-constrained market — qualifying an alternate from the same or a second SiC vendor is prudent for high-volume builds.","metaTitle":"STMicroelectronics SCT10N120 SiC N-Ch FET, 1200V 12A TO-247","metaDescription":"ST SCT10N120 SiCFET N-Channel 1200V 12A in TO-247-3. 690mOhm Rds(on) @ 6A. -55 to 200°C junction.
