Frequently Asked Questions
How does the 1700 V rating of SCT20N170AG compare to 1200 V SiC MOSFETs for 800 V EV bus architectures?
An 800 V EV DC bus with regenerative overvoltage transients can reach 900 V to 1000 V peak. The SCT20N170AG's 1700 V rating provides over 700 V of headroom above those peaks, whereas 1200 V devices leave only 200 V to 300 V margin. The extra headroom simplifies gate-driver snubber design and improves reliability in high-voltage traction inverters and on-board chargers.
What switching frequency can designers target with SCT20N170AG in a three-phase inverter compared to a silicon IGBT?
Silicon carbide technology in the SCT20N170AG enables switching frequencies above 20 kHz to 50 kHz without proportional increases in switching losses that would limit a comparable silicon IGBT. Higher switching frequency reduces filter inductor size by a factor proportional to frequency, allowing significant weight and volume reduction in the power stage for a 43 A, 1700 V converter.
Does SCT20N170AG carry AEC-Q101 qualification, and what does that mean for automotive supply-chain compliance?
Yes, SCT20N170AG is AEC-Q101 qualified, which means it has passed the Automotive Electronics Council's stress test suite covering ESD, high-temperature reverse bias, and thermal shock for discrete semiconductors. This qualification is a mandatory prerequisite for Tier-1 automotive supplier qualification processes, allowing the device to be designed into EV powertrain, charging, and safety-critical systems without additional component-level screening.
What is the thermal and mechanical benefit of the HiP247 package for a high-power, high-voltage PCB layout?
The HiP247 package used for SCT20N170AG features enlarged pin-to-pin creepage and clearance distances compared to the standard TO-247, reducing the risk of surface arcing at 1700 V operation. Its through-hole leads also provide a large thermal pad contact area, enabling junction-to-case thermal resistance below 0.4°C/W when paired with an appropriate heatsink, which is important for sustaining 43 A continuous drain current.
