Transphorm product offering
Product offeringCore offering
Transphorm designs and manufactures high-voltage Gallium Nitride (GaN) power semiconductor discretes based on its proprietary SuperGaN D-mode GaN-on-Si cascode architecture, spanning power levels from 25W to over 10+ kW. Its product portfolio includes 650V GaN FETs, GaN Bidirectional Switches (BDS), and supporting evaluation kits serving power conversion applications in AI data centers, electric vehicles, consumer electronics, industrial motor drives, and renewable energy systems. Since June 2024, the business has operated as a subsidiary of Renesas Electronics Corporation, with products distributed through Renesas' global sales channels.
Product overview
Transphorm develops high-voltage gallium nitride (GaN) power semiconductor technology that was acquired by Renesas Electronics in June 2024. The product portfolio centers on GaN Power Discretes based on the SuperGaN D-mode GaN-on-Si cascode architecture, spanning power ratings from 25W to over 10+ kW. Key products include the 650V GaN Bidirectional Switches (BDS) series featuring the TP65B110HRU 110mΩ device, Gen IV Plus 650V SuperGaN FETs, and supporting evaluation kits. The SuperGaN platform provides a robust normally-off architecture with integrated low-voltage silicon MOSFET front end, enabling compatibility with standard silicon drivers while delivering superior efficiency and performance over silicon, SiC, and e-mode GaN alternatives. The portfolio serves applications across consumer electronics (USB-C power adapters, UPS systems), industrial (motor drives, solar microinverters, digital power conversion), and automotive (EV onboard chargers, X-in-1 EV units).

Transphorm competitors and assessment
Company assessmentDirect peers
- Navitas Semiconductor: Navitas is a pure-play GaN power semiconductor company competing head-to-head with Transphorm across USB-PD, consumer, and higher-power applications using a different (e-mode, gate-driver-integrated) architecture versus Transphorm's cascode approach. It is the most direct publicly traded GaN peer.
- Efficient Power Conversion (EPC): EPC specializes in e-mode GaN FETs and ICs spanning similar power and voltage ranges as Transphorm's discretes, serving USB-PD chargers, motor drives, and high-frequency power conversion. It is one of Transphorm's closest technology and end-market competitors.
- Innoscience: Innoscience is one of the largest GaN-on-Si power device manufacturers globally with an integrated fab, competing directly with Transphorm across consumer, automotive, and industrial power applications. It represents the scale and price-pressure benchmark for the GaN discretes segment.
- Power Integrations: Power Integrations sells GaN-based power supply ICs for USB-PD chargers, industrial, and appliance applications, overlapping with Transphorm's consumer and industrial segments. It represents a fabless, IC-integrated alternative to Transphorm's discrete GaN strategy.
Broad incumbents
- Infineon Technologies: Infineon acquired GaN Systems and has a major SiC and GaN roadmap across industrial, automotive, and renewable-energy power conversion. Its broad power-semiconductor portfolio and automotive Tier-1 relationships make it the most significant incumbent competitor to Transphorm/Renesas.
- STMicroelectronics: STMicroelectronics is a major SiC power semiconductor incumbent with a growing GaN program serving automotive traction, industrial, and consumer power applications. It competes with Transphorm wherever wide-bandgap power conversion is specified.
- Wolfspeed: Wolfspeed is a leading pure-play SiC power semiconductor company targeting EV, industrial, and renewable energy applications that overlap directly with Transphorm's high-voltage opportunity. It is the most strategically threatening wide-bandgap alternative to GaN.
- onsemi (ON Semiconductor): onsemi is a major SiC and power semiconductor incumbent with strong traction in EV and industrial power conversion applications. It competes with Transphorm wherever SiC and GaN compete for the same power-conversion sockets.
- ROHM Semiconductor: ROHM is a Japanese power semiconductor leader with SiC and emerging GaN offerings across industrial and automotive markets. Its vertical integration and Japanese Tier-1 relationships make it a relevant comparable as Transphorm integrates into Renesas' Japanese distribution.
Others
- Renesas Electronics Corporation: Renesas acquired Transphorm in June 2024 to integrate GaN into its broader power semiconductor portfolio. While now the parent, Renesas is the platform through which Transphorm's technology is monetized, and its existing IGBT, Si, and SiC lines are adjacencies competing for the same customer sockets.
