GS66502B

650V Enhancement Mode GaN Transistor

The GS66502B is an enhancement mode GaN-on-silicon power transistor. The properties of GaN allow for high current, high voltage breakdown and high switching frequency. GaN Systems implements patented Island Technology® cell layout for high-current die performance & yield. GaNPX® packaging enables low inductance & low thermal resistance in a small package. The GS66502B is a bottom-side cooled transistor that offers very low junction-to-case thermal resistance for demanding high power applications. These features combine to provide very high efficiency power switching.

  • Ultra-low FOM Island Technology® die
  • Low inductance GaNPX® package
  • Easy gate drive requirements (0 V to 6 V)
  • Transient tolerant gate drive (-20 V / +10 V )
  • Very high switching frequency (> 100 MHz)
  • Fast and controllable fall and rise times
  • Reverse current capability
  • Zero reverse recovery loss
  • Small 5.0 x 6.6 mm2 PCB footprint
  • RoHS 6 compliant

APPLICATIONS

  • High efficiency power conversion
  • High density power conversion
  • AC-DC Converters
  • Bridgeless Totem Pole PFC
  • ZVS Phase Shifted Full Bridge
  • Half Bridge topologies
  • Synchronous Buck or Boost
  • Small-Medium UPS
  • Appliance Motor Drives
  • Single phase inverter legs
  • Fast Battery Charging
  • Class D Audio amplifiers
  • DC-DC converters

EVALUATION BOARD: GS665MB-EVB

650 V Universal Motherboard

This universal motherboard can be used with daughter cards (sold separately) to evaluate the entire GaN Systems 650 V family of GaN E-HEMT products.

COMPATIBLE WITH:

  • GS66504B-EVBDB
  • GS66508B-EVBDB

EVALUATION BOARD: GS66504B-EVBDB

650 V GaN E-HEMT Daughter Board

This product requires a motherboard (GS665MB-EVB)

The GS66504B-EVBDB daughter board consists of two GaN Systems 650V GaN Enhancement-mode HEMTs (part number GS66504B) and all necessary circuits including half bridge gate drivers, isolated power supplies and optional heatsink to form a functional half bridge power stage. It allows users to easily evaluate the GaN E-HEMT performance in any half bridge-based topology, either with the universal motherboard or the users’ own system design.

  • Serves as a reference design and evaluation tool as well as deployment-ready solution for easy insystem evaluation
  • Vertical mount style with height of 35mm, which fits in majority of 1U design and allows evaluation of GaN
  • E-HEMT in traditional through-hole type power supply board
  • Current shunt position for switching characterization testing
  • Universal form factor and footprint for all products
