Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (Diodes) (Nasdaq: DIOD) introduces the latest addition to its portfolio of Silicon Carbide (SiC) products: the DMWS120H100SM4 N-channel SiC MOSFET. This device addresses demand for higher efficiency and higher power density for applications such as industrial motor drives, solar inverters, data center and telecom power supplies, DC-DC converters, and electric vehicle (EV) battery chargers.

The DMWS120H100SM4 operates at a high voltage (1200V) and drain current (up to 37A) while maintaining low thermal conductivity (R_θJC = 0.6°C/W), making it well-suited for applications running in harsh environments. This MOSFET has a low R_DS(ON) (typical) of only 80mΩ (for a 15V gate drive) to minimize conduction losses and provide higher efficiency. In addition, the device has a gate charge of only 52nC to reduce switching losses and lower the package temperature.

This product is the first SiC MOSFET on the market in a TO247-4 package. The additional Kelvin sense pin can be connected to the source of the MOSFET to optimize the switching performance, thereby enabling even higher power densities.

The DMWS120H100SM4 is available at $21.50 in 20-piece quantities.
