Applications
The SCTWA40N120G2V-4 is targeted at high-voltage power conversion applications including EV onboard chargers, solar inverters, and industrial motor drives where silicon carbide's low switching losses reduce heat and improve efficiency. Its 1200V breakdown voltage and 36A continuous drain current handle demanding DC bus voltages up to 800V in three-phase inverter stages. The HiP247-4 package and built-in diode simplify thermal management and bill-of-materials in high-power designs.

Frequently Asked Questions
What is the on-resistance of the SCTWA40N120G2V-4 and how does SiC technology reduce switching losses versus silicon?
The SCTWA40N120G2V-4 has a typical RDS(on) of 62 mΩ and a maximum of 100 mΩ. Silicon carbide technology allows switching at higher frequencies with lower turn-on and turn-off losses compared to equivalent silicon IGBTs, reducing heat dissipation in 1200V inverter stages operating at tens of kilohertz.
Can the SCTWA40N120G2V-4 handle an 800V DC bus in a three-phase motor drive, given its 1200V rating?
Yes, the 1200V minimum DS breakdown voltage provides a comfortable safety margin above an 800V DC bus, and the 36A maximum drain current supports motor power levels up to approximately 20 kW in a well-designed inverter with adequate thermal management.
What thermal advantage does the HiP247-4 package offer for the SCTWA40N120G2V-4 in a heat-sink mounted design?
The HiP247-4 package connects the case directly to the drain, allowing the exposed metal case to be mounted flush against a heatsink for efficient thermal conduction, which is critical when dissipating the power losses of a 36A SiC MOSFET in a continuous operation scenario.
Does the SCTWA40N120G2V-4 include a built-in diode, and does that eliminate the need for an external freewheeling diode?
Yes, the SCTWA40N120G2V-4 has a built-in diode in a single-device configuration, which acts as the body diode for freewheeling current in bridge topologies, reducing external component count and PCB area in EV charger and solar inverter half-bridge stages.
