GAN111-650WSB 개요
A GaN FET (Gallium Nitride Field-Effect Transistor) is a wide-bandgap power transistor that operates as a higher-frequency, higher-efficiency successor to the silicon MOSFET in the power semiconductor hierarchy. Within the taxonomy GaN FET -> HEMT -> power transistor -> discrete semiconductor -> power management, GaN devices deliver lower on-resistance per unit area, faster switching edges, smaller magnetic components, and reduced conduction/switching losses compared with silicon superjunction MOSFETs at the same voltage rating.
Key features of the GAN111-650WSB include 650 V drain-source blocking voltage, 97 mΩ typical on-resistance (RDS(on)), and a normally-off architecture that simplifies gate drive and failsafe behavior. The TO-247 package offers industry-standard through-hole mounting with robust thermal performance for high-current applications. The cascode H2 HEMT topology provides a hardened gate that withstands standard silicon MOSFET gate-drive levels.
Typical applications include high-efficiency AC-DC and DC-DC converters, server and telecom switch-mode power supplies (SMPS), photovoltaic microinverters and string inverters, on-board chargers (OBC) for electric vehicles, and industrial motor drives. The 650 V rating also makes it suitable for three-phase PFC front ends and totem-pole bridgeless PFC topologies.
When designing with this device, ensure the gate driver can supply sufficient pull-down current to handle high dv/dt transitions, and place the gate-source loop as small as possible to minimize ringing. Compared with silicon superjunction MOSFETs of similar RDS(on), the GAN111-650WSB delivers substantially lower switching losses and supports higher switching frequencies, reducing magnetic component size.

일반적인 애플리케이션
GAN111-650WSB 적합 용도: 6 애플리케이션s: Totem-Pole Bridgeless PFC Front End, Server & Telecom SMPS Primary Switch, Solar String Inverter DC-AC Stage, EV On-Board Charger (OBC) PFC Stage, Industrial Motor Drive Inverter, Datacenter 48 V Intermediate Bus Converter.
Totem-Pole Bridgeless PFC Front End
The GAN111-650WSB's cascode HEMT H2 topology eliminates body-diode reverse-recovery, making it ideal for totem-pole bridgeless PFC at 100-300 W to several kW. With 97 mΩ RDS(on) and 650 V blocking, the device supports CCM operation at 100 kHz-1 MHz switching frequency, reaching 98.5%+ efficiency with smaller magnetics than 650 V silicon superjunction MOSFETs. Place GaN FETs in the high-frequency leg; use standard silicon rectifiers in the slow leg. The standard MOSFET-compatible gate drive simplifies driver selection versus e-mode GaN devices.
추천
Server & Telecom SMPS Primary Switch
In 1-3 kW server and telecom SMPS, the GAN111-650WSB serves as the primary-side switch in CCM hard-switched converters or as the 400 V PFC switch. Its 97 mΩ RDS(on) at 650 V class delivers 30-50% lower switching losses than silicon superjunction MOSFETs, enabling higher switching frequencies (200-500 kHz) and 20-40% smaller magnetic components. The TO-247 package offers robust thermal dissipation at 21 A continuous drain current and supports standard MOSFET gate drivers, reducing design complexity.
추천
Solar String Inverter DC-AC Stage
In photovoltaic string inverters and microinverters, the GAN111-650WSB functions in the DC-AC bridge leg switching at 50-200 kHz. Its 650 V blocking handles 600 V DC bus transients with margin, and 97 mΩ RDS(on) reduces conduction losses under partial-load conditions where inverter efficiency matters most. The normally-off cascode topology ensures fail-safe behavior on grid loss events. Nexperia GaN FETs have demonstrated field reliability in solar inverters to LEO and terrestrial PV systems.
추천
EV On-Board Charger (OBC) PFC Stage
In 3.3 kW to 11 kW EV on-board chargers, the GAN111-650WSB excels in the PFC and DC-DC primary stages where high efficiency and high power density are mandated. Its 97 mΩ RDS(on) supports continuous operation above 3 kW, and its cascode HEMT H2 topology enables bidirectional totem-pole PFC and DAB topologies for V2X applications. The TO-247 through-hole package handles thermal loads in automotive underhood environments with proper heatsinking.
추천
Industrial Motor Drive Inverter
In 1-5 kW industrial motor drives, the GAN111-650WSB is suitable for the 400-480 V AC three-phase inverter leg where high switching frequency (>20 kHz) reduces motor winding losses and audible noise. The 97 mΩ RDS(on) and 21 A continuous rating cover most sub-3 kW drives; 650 V blocking provides 30% margin above rectified 480 V bus. GaN FETs also reduce dead-time, improving low-speed torque ripple versus silicon IGBT solutions.
추천
Datacenter 48 V Intermediate Bus Converter
For 48 V to 12 V or 48 V to 5 V bus converters in AI/datacenter applications, the GAN111-650WSB can serve as the primary switch in 1-2 kW LLC or full-bridge topologies. Its 650 V rating provides headroom for 48 V input plus transient overshoot, while 97 mΩ RDS(on) supports high switching frequency (>500 kHz) for planar magnetics. GaN FETs at this frequency shrink the bus converter by 30-50% versus silicon solutions, addressing AI rack power-density pressure.

설계 노트
GaN FETs have far higher dv/dt and di/dt than silicon MOSFETs - place the gate driver as close as possible to the gate pin to minimize gate-loop inductance. Estimated: at 100 V/ns dv/dt, each 1 nH of gate-loop inductance generates 100 V ringing on the gate. Target gate-loop inductance below 5 nH by routing gate and source return on adjacent PCB layers with minimum loop area.
TO-247 packages require substantial heatsinking at 21 A continuous current. Estimated: at 21 A and 97 mΩ RDS(on), conduction loss is approximately 43 W, requiring a heatsink with thermal resistance under 2 C/W to keep junction rise below 80 C above ambient. Use thermal interface material rated for 6 W/m-K or better, and consider a forced-air solution for sustained high-current operation.
Do not exceed VGS ratings of the cascode MOSFET portion; the Nexperia GAN111-650WSB accepts standard ±20 V gate drive. Avoid slow gate transitions - turn-off propagation delay mismatch can cause shoot-through in half-bridge configurations. Use a gate driver with matched propagation delays and split turn-on/turn-off resistors to optimize switching speed without causing excessive ringing.
The TO-247 through-hole package requires adequate copper pad area on both source and drain sides. Estimated: at 100 kHz switching with 21 A, recommend at least 100 mm² of 2 oz copper pour connected to the drain tab, plus a 25 mm² source-side pour. Keep the switching-node copper minimal to avoid antenna-mode EMI emissions from the high dv/dt transitions.
GaN FETs produce higher EMI than silicon MOSFETs due to faster edge rates. Estimated: at 100 V/ns vs 20 V/ns for an equivalent silicon MOSFET, conducted EMI above 30 MHz can be 10-20 dB higher. Mitigate with a small common-mode choke on input/output lines, a small R-C snubber across the device, and ensure the PCB has a low-impedance return path for high-frequency switching currents.
