SCTW100N65G2AG Overview
A silicon carbide MOSFET is a wide-bandgap power transistor that switches high voltages and currents with substantially lower switching and conduction losses than a silicon MOSFET or IGBT of comparable rating. SiC technology sits in the power semiconductor hierarchy below IGBT and silicon MOSFET for high-voltage (>600 V) applications, offering higher switching frequency capability, lower switching losses, and better thermal conductivity. AEC-Q101 qualified variants like the SCTW100N65G2AG are specifically designed for harsh automotive environments such as traction inverters and on-board chargers.
Key differentiating specifications include 20 mΩ typical RDS(on) at 25 °C, very fast and robust intrinsic body diode, extremely low gate charge and input capacitance, and a 650 V repetitive breakdown voltage with 100 A continuous drain current. The HiP247 through-hole package supports 420 W power dissipation with a low junction-to-case thermal resistance optimized for forced-air or liquid-cooled heatsinks typical in EV power electronics.
The device's 2nd-generation SiC trench architecture minimizes RDS(on) per unit area and integrates a robust intrinsic body diode, eliminating the need for external anti-parallel diodes in many bridge-leg applications. Compared with silicon IGBTs of similar voltage class, the SiC MOSFET reduces switching losses by 50-70 % at the same frequency, allowing smaller magnetics and higher converter power density in traction and charging systems.
Typical applications include on-board chargers (OBC) for electric vehicles, EV traction inverters, DC-DC converters for xEV powertrains, photovoltaic (PV) string inverters, industrial servo drives, and high-frequency telecom power supplies. AEC-Q101 qualification makes it directly suitable for automotive environments per customer-required quality levels and PPAP documentation.
When designing around this part, gate-drive voltage must reach +18 V typical for the rated RDS(on), with a 0 V or negative turn-off recommended to ensure noise immunity at high dV/dt. A small gate-source resistor (typically 10 Ω) plus proper PCB layout minimize ringing and overshoot on the gate.

Typical Applications
SCTW100N65G2AG is suitable for 7 applications: EV On-Board Charger (OBC), EV Traction Inverter, xEV DC-DC Converter, Solar String Inverter, Industrial Servo / Variable-Frequency Drive, Telecom / Server Power Supply, Industrial Battery Charger / Energy Storage.
EV On-Board Charger (OBC)
The SCTW100N65G2AG's 650 V VDS rating and 100 A continuous drain current suit it for high-voltage stages of on-board chargers (typically 6.6 kW to 22 kW) operating from 400 V or 800 V EV bus rails. With RDS(on) of 20 mΩ at 25 °C, conduction loss stays low even at full load, and 2nd-gen SiC switching characteristics cut switching losses by 50-70 % versus silicon IGBT alternatives - improving OBC efficiency by 1-2 % and reducing thermal management cost. The AEC-Q101 qualification plus HiP247 through-hole package supports automotive-volume heatsink mounting under the hood or in the charging-cable enclosure.
Recommended
EV Traction Inverter
The SCTW100N65G2AG is rated for the high-current, high-frequency half-bridge positions in 100-200 kW traction inverters driving electric-vehicle permanent-magnet or induction motors. Its 100 A continuous DC rating, 650 V VDS margin above 400 V bus operation, and 420 W dissipation capability map directly to the inverter's per-switch requirements, while the HiP247 package supports liquid-cooled cold-plate mounting. The very robust intrinsic body diode with low Qrr enables deadtime-optimized switching, reducing torque ripple and audible noise in motor drive applications.
Recommended
xEV DC-DC Converter
The SCTW100N65G2AG serves as the primary switching device in 400 V to 12 V / 48 V high-voltage DC-DC converters used in mild-hybrid and full-electric vehicles. Its 650 V rating handles 400 V bus transients with margin, and the low gate charge supports switching frequencies of 100 kHz or higher - shrinking the size and cost of the converter's isolation transformer and output inductor. SiC switching loss reduction translates directly to higher converter efficiency (typically 96 %+), easing thermal budgets in cramped underbody enclosures.
Recommended
Solar String Inverter
The SCTW100N65G2AG's 650 V breakdown voltage enables safe operation from 1500 V DC string open-circuit conditions when properly derated, and 100 A continuous rating supports 50-100 kW inverter power stages used in commercial and utility-scale PV plants. SiC switching loss reduction allows higher switching frequency, reducing LCL filter size and lowering system BOM cost. The HiP247 package accepts standard TO-247 heatsink mounts, simplifying mechanical integration into existing inverter production lines migrating from silicon IGBT to SiC MOSFET technology.
Recommended
Industrial Servo / Variable-Frequency Drive
The SCTW100N65G2AG supports high-dynamic-response servo drives and industrial VFDs where switching frequency above the audible band and low switching losses reduce motor heating and acoustic emissions. With 100 A continuous rating, it fits drives up to approximately 30 kW at 480 V three-phase input. The robust intrinsic body diode simplifies the half-bridge layout and supports regenerative braking modes common in industrial servo applications; AEC-Q101 qualification indicates SiC technology reliability that exceeds typical industrial-grade silicon IGBT counterparts in the same position.
Recommended
Telecom / Server Power Supply
The SCTW100N65G2AG fits high-efficiency 3-5 kW rectifier stages used in -48 V telecom and hyperscale-data-center power supplies where efficiency drives operating-cost reduction. Its 650 V rating supports universal AC input (85-265 V) PFC and LLC converter stages, while low Qg and Qrr reduce driver losses and improve light-load efficiency - critical for meeting 80 PLUS Titanium and ETSI EN 300 132-2 efficiency targets. The HiP247 package, while through-hole, is increasingly accepted in 3 kW+ server PSU designs that already use TO-247-package parts.
Recommended
Industrial Battery Charger / Energy Storage
The SCTW100N65G2AG supports bidirectional DC-DC converter stages in industrial lithium-ion battery chargers and stationary energy-storage systems (ESS) where high efficiency and bidirectional current handling are essential. The very fast body diode intrinsically supports synchronous-rectifier-mode reverse-current flow without an additional anti-parallel diode, reducing BOM and conduction losses. AEC-Q101 qualification ensures long-term reliability under thermal cycling typical in battery-cabinet operating environments with daily charge/discharge profiles.

Key Differentiators
- Automotive-grade AEC-Q101 qualification in the same HiP247 footprint (vs SCTWA100N65G2AG)
- Higher continuous drain current rating in same HiP247 footprint (vs SCTW70N65G2V-7AG)
- Lower RDS(on) at 25 °C for higher-current variants (vs SCTW120N65G2AG)

Design Notes
Estimated: at ID = 100 A continuous and RDS(on) = 20 mΩ (nominal, ignoring RDS(on) temperature rise), conduction loss is approximately 200 W at 25 °C. The HiP247 package's junction-to-case thermal resistance is below 0.5 °C/W per ST datasheet, so for a 125 °C liquid cold plate the steady-state junction temperature rise above case is roughly 100 °C - well within SiC's 200 °C rating. Forced-air cooling requires a substantial heatsink (>1 °C/W) plus airflow >2 m/s; for sustained 100 A in traction drives, design for liquid cooling.
Use a kelvin source connection from pin 3 directly to the gate-driver return, NOT to the high-current source return path. Keep the gate-loop loop-area under 1 cm² to control ringing from the input capacitance (~10 nF class). Place a 10 Ω gate-source resistor directly at the gate pin plus an optional 10 Ω gate-drive series resistor to damp dV/dt-induced ringing above 50 V/ns; SiC MOSFETs' high dV/dt and dI/dt easily couple stray inductance into the gate.
Drive VGS to +18 V (not +12 V) to achieve the rated 20 mΩ RDS(on). Apply a 0 V to -3 V turn-off voltage to ensure robust noise immunity under high dV/dt - the absolute maximum VGS range is -10 V to +22 V per the datasheet. Use a gate driver with at least 4 A sink/source capability for switching frequencies above 50 kHz; the gate charge Qg plus high dV/dt demands higher driver current than silicon MOSFET equivalents.
Do not substitute a silicon IGBT in this position without re-validating the gate-drive circuit (voltage levels differ). Do not assume HiP247-compatible through-hole parts from other vendors share the same gate-drain-source pinout order - Infineon TO-247-3 SiC MOSFETs may have gate on pin 1, gate on pin 2, or gate on pin 3 depending on product, so verify against the device datasheet before PCB assembly.
Although the part includes a robust intrinsic body diode, external anti-parallel SiC Schottky diodes are sometimes added in parallel to further reduce deadtime-related reverse-recovery losses in very-high-frequency designs. In half-bridge legs, add 1-2 Ω of deadtime (typ. 100-200 ns) to prevent shoot-through given SiC MOSFETs' very fast switching edges, which is significantly shorter than equivalent silicon IGBT bridges.
