Watech has successfully mass-produced 1200V and 650V field-stop IGBTs (FS-IGBTs). These devices utilize internationally leading 7th-generation fabrication technology with refined trench gate design. This innovative architecture substantially reduces both conduction and switching losses while significantly enhancing short-circuit withstand capability, making the FS-IGBT particularly well-suited for industrial control module applications.

The FS-IGBT technology has now been widely implemented across multiple sectors including photovoltaic inverters, uninterruptible power supplies (UPS), general-purpose variable frequency drives, servo drives, and automotive air conditioning systems. This demonstrates the critical role this technology plays in energy conversion, power control, and automotive electronics, providing advanced solutions for enhancing efficiency and performance.
