San Francisco-based Pakal Technologies has announced a partnership with Prohubs to handle distribution and market development for its silicon power semiconductors. The agreement focuses on the IGTO, a drop-in replacement technology designed for existing Fieldstop IGBT architectures.
Why it matters
As AI infrastructure and widespread electrification drive global electricity demand, this partnership seeks to scale the adoption of high-efficiency power semiconductors. By leveraging Prohubs' commercialization expertise in Taiwan, Pakal aims to broaden the use of its IGTO technology in industrial and high-voltage energy applications.
Pakal IGTO devices operate across a voltage range of 650 to 2500 Volts. The hardware is designed as a drop-in upgrade for Fieldstop IGBTs—power transistors commonly used in high-efficiency switching—with planned future performance demonstrations for applications exceeding 3.0 kV.
The players
Pakal Technologies
A San Francisco-based semiconductor firm specializing in silicon power transistor architectures for energy infrastructure.
Prohubs
A Taiwan-based service provider focused on semiconductor commercialization, design-in support, and market development.
Hitachi Energy
A global technology leader in power grids and energy storage systems that has partnered with Pakal for high-voltage application testing.
The details
The IGTO technology functions as a silicon-based power semiconductor that acts as a functional replacement for Fieldstop IGBTs, or Insulated Gate Bipolar Transistors—semiconductor devices used as electronic switches for high-power efficiency. Prohubs will manage the design-in process, which involves early-stage technical support to integrate specific hardware into customer systems, alongside distribution and customer engagement. Pakal previously refined these designs through collaborations with Hitachi Energy on high-voltage power electronics.

The Tech Race
The transition to IGTO technology represents a direct competitive attempt to improve upon the established Fieldstop IGBT performance curve. Pakal's ability to scale this architecture above 3.0 kV will determine its competitiveness against incumbent power semiconductor roadmaps.
Industrial designers and engineers can expect faster access to IGTO components through Prohubs' established distribution channels in Taiwan. The move primarily impacts high-voltage infrastructure sectors, with broad availability dependent on the upcoming 3.0 kV performance validations.
The takeaway
This partnership shifts the focus from laboratory development toward mass-market commercialization of high-voltage semiconductors. Readers should watch for Pakal’s upcoming technical demonstrations for architectures exceeding 3.0 kV to confirm the platform’s scalability.
