STMicroelectronics Releases New STPOWER PowerGaN Transistors

Gallium Nitride (GaN) products offer improved efficency, higher voltage operation and faster switching speeds

New STPOWER PowerGaN Transistors

STMicroelectronics' has released a new family of GaN power semiconductors in the STPOWER portfolio that can significantly reduce energy use and enable slimmer designs in a large range of electronic products. Target applications include consumer equipment such as chargers, external power adapters for PCs, LED-lighting drivers, and power supplies inside televisions and home appliances. This equipment is produced in high volumes worldwide and, with greater efficiency, will require less power and subsequently realize significant CO2 savings. In higher-power applications, STMicroelectronics PowerGaN devices also benefit telecom power supplies, industrial motor drives, solar inverters, and electric vehicles and chargers.

Commercializing GaN-based products is the next frontier for power semiconductors, and we are ready to realize the potential of this exciting technology. Today ST is announcing the first product in a new family, belonging to the STPOWER portfolio, that can deliver breakthrough performance for a large variety of power supplies across consumer, industrial, and automotive applications, said Edoardo Merli, Power Transistor Macro-Division General Manager and Group Vice President of STMicroelectronics' Automotive and Discrete Group. We are committed to progressively building up our PowerGaN portfolio to enable customers to design more efficient, smaller power supplies everywhere.

Key Features of the SGT120R65AL e-mode PowerGaN transistor include

  • Enhancement mode normally off transistor
  • 120mΩ maximum on-resistance
  • 15A maximum current capability
  • Very high switching speed
  • High power management capability
  • Extremely low capacitances
  • Kelvin source pad for optimum gate driving
  • Zero reverse recovery charge
