Broadcom & Nexperia – Building bridges for the best solution
Nexperia’s 650V 33mOhm GaN FET & Broadcom’s ACFJ-3262
This is a half-bridge evaluation board featuring Nexperia GaN FET, GAN039-650NBB and 10A gate drive optocoupler, ACFJ-3262.
The evaluation board uses a dual-channel ACFJ-3262 to drive both top and bottom bridge GaN FETs directly. Each channel of the ACFJ-3262 has two outputs to turn-on and off the GaN efficiently and reliably. The ACFJ-3262 has an UVLO of less than 10V, which is suitable for the 12V VGS operation of the GaN FET. It has more than 100kV/µs of noise immunity for fast switching dv/dt.
The GAN039-650NBB is a 650 V, 33 mΩ GaN FET in a CCPAK1212 package. It is a normally off device that combines Nexperia’s latest high-voltage GaN HEMT H2 technology and low-voltage silicon MOSFET technologies, offering superior reliability and performance.
Features
- ACFJ-3262, 10A dual-channel isolated gate drive optocoupler
- GAN039-650NBB, 650 V, 33 mΩ GaN FET
- Double pulse test for high slew rate dv/dt and Eon/Eoff performance
Applications

Analog & Power Management
The era of digitalisation is ever advancing, almost as if our world were solely represented and controlled by ones and zeros. Every physical variable – be it an audio signal, temperature, voltage – is an analog value.

Motor Control Solutions
Digital motor control can be defined as a drive system that combines an electric motor with power electronics for its energy delivery and processor units for motion control, as well as sensor and communication interfaces.

Broadcom Going Green
Broadcom optocouplers are the ideal fit for an array of green applications ranging from solar and wind inverters, energy storage, automotive electric vehicles and charging and power supplies.
