GaN Systems Power Transistor Prices Now Below $1, A Boon To AC Adapters For Smartphones

Written by Stephen Vicinanza

GaN Systems produces Gallium Nitride power transistors, it announced their high volume, low current GaN transistors have now tumbled to below a single dollar.

This type of transistor is used in many consumer and industrial applications, including GaN chargers, AC adapters for smartphones, and laptop battery and power applications.

Many consumer, enterprise, and industrial market customers now increasing manufacturing and production GaN systems see further reductions in prices.

While GaN’s advantages include reductions in system costs, improved power density, and power efficiency, many power system manufacturers have waited on utilizing the GaN transistors. They were waiting for the GaN products to reach silicon pricing in order to start implementing the GaN transistors.

A good example of a GaN portfolio entry, in the low-power GaN transistor lines, is the GS61004B. A 100V enhancement-mode GaN Transistor.

The GS61004B is a GaN-on-silicon power transistor. The properties of the transistor allow for high current, high voltage breakdown, and high switching frequency. The GaN GS61004B has innovative Island Technology. This technology cell layout realizes high-current die and high yield. The GaNPX packaging enables low- inductance and low thermal resistance in a small package.

The GS61004B is a bottom-cooled transistor with low junction-to-case thermal resistance for demanding high-power applications. Some of the applications these transistors can be used in are listed below.

  • Smart home
  • Fast battery charging
  • Solar Power
  • Enterprise and networking power
  • Industrial motor drives
  • Class D audio amplifiers
  • Uninterruptable power supplies

The features of the GS61004B include

  • Ultra-low FOM Island Technology die
  • Low Inductance GaNPX package
  • High switching frequency (>10 MHz)
  • Transient tolerant gate drive (-20 V / +10V)
  • Simple gate drive requirements (0V to 6V)
  • Reverse current capable
  • Fast and controllable fall and rise times
  • RoHS 3 (6+4) compliant
  • Zero reverse recovery loss
  • Small 4.6 x 4.4 mm2 PCB footprint
