GAN111-650WSBQ - 650V 97mOhm GaN FET TO-247 | Nexperia
MPN: GAN111-650WSBQ ✓ Hoạt độngGAN111-650WSBQ Tóm tắt
A GaN FET is a power transistor built on gallium nitride, a wide-bandgap (WBG) semiconductor with a bandgap of roughly 3.4 eV versus 1.1 eV for silicon. Within the power-semiconductor hierarchy (transistor -> FET -> wide-bandgap power transistor -> GaN HEMT), GaN devices switch faster and with lower switching losses than silicon MOSFETs or IGBTs, enabling higher-frequency power conversion with smaller magnetics.
The GAN111-650WSBQ combines Nexperia's high-voltage GaN HEMT H2 technology with an integrated low-voltage silicon MOSFET in a cascode configuration. The cascode stack delivers a true normally-off gate behavior, allowing the device to be driven with a conventional gate drive voltage of 10 V like a standard silicon MOSFET, simplifying gate-driver selection compared with direct-drive e-mode GaN parts.
Key differentiating specifications include the 97 mOhm RDS(on) figure of merit, the 650 V avalanche-classed drain rating, a wide operating temperature range of -55 C to +175 C, and the rugged TO-247 through-hole package that simplifies thermal design and prototyping compared with SMD GaN packages.
Typical applications include high-efficiency switched-mode power supplies (SMPS), totem-pole bridgeless power factor correction (PFC) stages, LLC resonant converters, solar / renewable-energy inverters, and servo or industrial motor-drive front ends where high-frequency, high-voltage switching directly reduces converter size and loss.
When designing with this device, minimize gate-loop and power-loop inductance, and provide a negative or zero-voltage gate turn-off to suppress dv/dt-induced turn-on; verify board layout against the manufacturer datasheet layout guidance for high-frequency GaN switching.

Ứng dụng tiêu biểu
GAN111-650WSBQ phù hợp cho 6 Áp dụngs: Totem-Pole Bridgeless PFC, LLC Resonant Converters, Solar and Renewable Energy Inverters, Industrial Motor Drives, High-Density SMPS / Telecom Rectifiers, High-Voltage Test and Prototype Platforms.
Totem-Pole Bridgeless PFC
The GAN111-650WSBQ is a strong fit for the fast switching leg of a continuous-conduction-mode totem-pole bridgeless PFC stage. Its GaN HEMT H2 cascode technology has near-zero reverse-recovery charge, eliminating the body-diade recovery loss that makes silicon MOSFETs unsuitable in this topology at the 650 V class. With 97 mOhm RDS(on) and 21 A continuous rating, a single device serves several-hundred-watt to kilowatt PFC front ends. Placed in a tight commutation loop and driven with a 10 V conventional gate driver, it sustains 65-100 kHz CCM switching with low loss; the main trade-off is strict layout discipline to control loop inductance and dv/dt.

LLC Resonant Converters
In half-bridge and full-bridge LLC resonant converters for server PSUs, adapters and LED drivers, the GAN111-650WSBQ provides 650 V blocking with 97 mOhm conduction at a ZVS operating point. Because LLC achieves zero-voltage switching, the GaN FET's low output charge and cascode reverse-conduction behavior minimize residual losses while allowing switching frequencies well above 100 kHz, shrinking the resonant inductor and transformer. The TO-247 through-hole package simplifies attaching a heatsink for the 107 W dissipation class. Designers should verify ZVS over the full load range, since loss of ZVS sharply raises turn-on loss in GaN devices at high bus voltage.

Solar and Renewable Energy Inverters
Solar micro-inverter and string-inverter power stages benefit from the GAN111-650WSBQ's 650 V rating, which directly accommodates 400 V DC-link bus systems with margin. The 97 mOhm RDS(on) keeps conduction loss low during MPPT boost and DC-AC stages, while GaN's fast switching enables compact, high-frequency magnetics important for rooftop and wall-mounted enclosures. Operating from -55 C to +175 C supports harsh outdoor thermal environments. Because GaN lacks a body diode, designers must implement defined freewheeling paths and verify dead-time logic; in return they gain very low reverse-recovery loss in hard-switched boost stages running at tens to hundreds of kilohertz.

Industrial Motor Drives
For servo drives and industrial inverters, the GAN111-650WSBQ can serve in the DC-link chopper, braking stage, or high-frequency inverter legs of 400 V-class systems. Its normally-off, 10 V-driven gate behaves like a silicon MOSFET, easing migration from existing IGBT or MOSFET drivers. GaN switching speed permits higher PWM frequencies, which reduces acoustic noise and current ripple in motor windings. The TO-247 package with 107 W dissipation capability simplifies mounting on existing extruded heatsinks. Designers should limit dv/dt-induced issues with careful gate turn-off impedance and verify gate-drive robustness against the fast switching edges inherent to GaN HEMT technology.

High-Density SMPS / Telecom Rectifiers
Telecom rectifiers and high-density AC-DC power supplies push for maximum watts per cubic inch, and the GAN111-650WSBQ addresses this by allowing switching frequencies that shrink transformers and EMI filters. With 650 V / 97 mOhm / 21 A ratings, one device class covers 500 W to multi-kilowatt brick and shelf power systems on a 400 V bus. The through-hole TO-247 format is common in current telecom power platforms, making the part retrofittable into existing thermals. The cascode structure's conventional 10 V gate drive lets designers reuse proven MOSFET driver circuits, reducing qualification risk when upgrading silicon platforms to GaN efficiency levels.

High-Voltage Test and Prototype Platforms
The TO-247-3L through-hole package of the GAN111-650WSBQ makes it especially convenient for evaluation boards, lab prototypes, and test fixtures for 650 V GaN switching research. Engineers can socket or solder the device, attach clip-on or bolted heatsinks, and probe gate and switching nodes directly, which is far harder with SMD GaN parts. With 97 mOhm RDS(on) and a 10 V conventional gate interface, the device pairs with standard MOSFET bench drivers for double-pulse testing of 400 V bus systems up to 21 A. This makes it a common first article for validating gate-driver and layout concepts before SMD production GaN parts are selected.

Ghi chú thiết kế
GaN switching speed makes power-loop inductance the dominant cause of voltage overshoot. Keep the commutation loop (GAN111-650WSBQ plus its freewheeling companion device and DC-link capacitor) as physically small as possible; use laminated bus structures or tight parallel-plane returns. Place the gate driver within a few millimeters of pin 1 and use a dedicated source/Kelvin return to pin 3 rather than sharing the power ground path, so the gate loop does not enclose power-loop flux that causes spurious turn-on at high di/dt.
The GAN111-650WSBQ has no intrinsic body diode; reverse conduction occurs through the channel with a forward voltage set by the gate drive. Do not rely on diode-like reverse recovery behavior inherited from silicon designs. In half-bridge topologies, guarantee dead time is sufficient for ZVS or defined commutation, and verify the reverse-conduction loss in your efficiency budget. Also remember the TO-247 tab is at drain potential - isolate the heatsink or use an insulated pad when the drain sits on a 400 V rail.
Estimated: at 10 A RMS, conduction loss alone is I2 x RDS(on) = 100 x 0.097 = about 9.7 W; add switching loss at your operating frequency and voltage. With a package capability of 107 W (Ta), a modest heatsink on the TO-247 tab with thermal grease and forced airflow is normally sufficient for tens of watts of dissipation. Derive the exact junction-to-case thermal resistance from the Nexperia datasheet thermal table and verify junction temperature stays below the 175 C maximum with at least 20-30 C design margin.
