CGD65B130SH2 Overview
A GaN HEMT (Gallium Nitride High Electron Mobility Transistor) is a wide-bandgap power transistor whose two-dimensional electron gas (2DEG) channel delivers far higher switching speed, lower gate charge, and lower on-resistance per area than silicon MOSFETs of the same voltage class. The CGD65B130SH2 belongs to the power semiconductor family, sitting in the power management hierarchy between low-voltage logic MOSFETs (sub-200V) and high-voltage SiC MOSFETs (typically >900V). It is engineered as a normally-off enhancement-mode device for easy drop-in replacement of silicon superjunction MOSFETs in 400 V and 500 V bus designs.
Per the manufacturer datasheet, the CGD65B130SH2 specifies 12 A continuous drain current at 25°C, total gate charge Qg = 1.9 nC, gate threshold voltage of 2.2 V to 4.2 V, and RDS(on) range of 130 to 350 mΩ across drive and temperature conditions. The 650 V rating provides substantial derating margin for universal-input PFC stages operating from rectified 230 VAC mains, where bus voltages reach 400 V. The 8-DFN (5x6) package with bottom-side cooling pad supports high-density surface-mount reflow and reduces parasitic source inductance, which is critical for clean switching at >100 kHz.
The architecture exploits GaN's high critical electric field and 2DEG channel mobility to achieve low conduction and switching losses simultaneously, enabling hard-switched topologies such as totem-pole PFC and LLC converters to operate at multi-hundred-kHz frequencies without the thermal penalties imposed by silicon superjunction MOSFETs. The integrated current-sense and NL³ protection circuits reduce external component count in motor-drive and synchronous-rectification applications.
Typical applications include AC-DC and DC-DC converters, totem-pole bridgeless PFC front ends, server and telecom switched-mode power supplies, photovoltaic micro-inverters and string inverters, on-board chargers for electric vehicles, motor drives, and class-D audio amplifiers.
When designing with this part, confirm gate-drive voltage of 12 V is available and place the gate drive loop return directly under the source connection. Decouple the gate-driver supply locally and follow Cambridge GaN Devices' reference layout for the 8-DFN (5x6) footprint.

Typical Applications
CGD65B130SH2 is suitable for 6 applications: Totem-Pole Bridgeless PFC, Server / Telecom SMPS, Photovoltaic String Inverters, EV On-Board Chargers, Brushless DC Motor Drives, Class-D Audio Amplifiers.
Totem-Pole Bridgeless PFC
The CGD65B130SH2 is a primary switch candidate for totem-pole bridgeless PFC stages fed from 230 VAC mains. Its 650 V VDS rating provides comfortable headroom above the 400 V rectified bus, and the 1.9 nC total gate charge enables switching frequencies well above 100 kHz, shrinking the PFC inductor size and improving power density. The lack of body-diode reverse-recovery charge removes the cross-conduction losses that plague silicon superjunction implementations, while the on-chip current-sense output supports cycle-by-cycle current-mode control. Compared with a silicon 600 V/20 A MOSFET, the CGD65B130SH2 in the same 8-DFN footprint cuts switching losses in half and eliminates diode bridge losses entirely.
Recommended
Server / Telecom SMPS
For 1-3 kW 48 V output server and telecom switched-mode power supplies, the CGD65B130SH2 drives the primary side of an LLC converter where its 650 V rating is over-specified for 380-400 VDC telecom bus inputs. The 1.9 nC Qg allows the LLC to run at 200 kHz+, shrinking the resonant tank and the transformer footprint. The NL³ protection circuit on the CGD65B130SH2 cuts over-current shutdown time and reduces the host controller interrupt latency, which matters when designing for 80 PLUS Titanium efficiency targets. The 8-DFN (5x6) footprint is footprint-compatible with the silicon 600 V superjunction MOSFETs that the server PSU community has historically used, easing migration.
Recommended
Photovoltaic String Inverters
In 5-10 kW residential and commercial photovoltaic string inverters, the CGD65B130SH2 forms the boost and DC-DC converter switches, with multiple parts in parallel possible thanks to its positive temperature coefficient on-resistance. The 650 V breakdown rating is suitable for 600 VDC max solar input strings, and the low RDS(on) of 55 mΩ (typical) limits I²R conduction losses during peak solar generation. The integrated current-sense output of the CGD65B130SH2 simplifies MPPT algorithm implementation by providing an internal drain-current sense that does not require an external shunt or sense-FET circuit.
Recommended
EV On-Board Chargers
The CGD65B130SH2 is suitable for 6.6-22 kW EV on-board charger modules where 400 V and 800 V powertrain buses are charged from 230 VAC mains. The 650 V VDS of the CGD65B130SH2 covers the rectified 400 V bus with margin for a 6.6 kW OBC, and a pair of these parts in a totem-pole arrangement handles the full input current at high switching frequency, reducing the size of the PFC inductor and the DC-DC transformer. Cambridge GaN Devices' automotive-qualified variant (CGD65B130SH2-Q, same 8-DFN footprint) is recommended for AEC-Q100 application environments.
Recommended
Brushless DC Motor Drives
The CGD65B130SH2 can replace silicon IGBTs and MOSFETs in 400-500 V brushless DC motor drives for industrial automation and e-mobility. Its low Qg supports 50-100 kHz PWM frequencies, which shrink the motor's acoustic signature and reduce the torque ripple. The 12 A continuous current rating covers fractional-horsepower industrial BLDC servos up to 1 kW, while the integrated current-sense of the CGD65B130SH2 simplifies FOC algorithm implementation by feeding the controller's shunt-free current path.
Recommended
Class-D Audio Amplifiers
In 200-500 W class-D audio amplifiers, the CGD65B130SH2 is used in the output half-bridge where its low gate charge (1.9 nC) and absence of reverse-recovery charge enable 500 kHz+ switching frequencies. These high PWM frequencies move the LC filter cutoff above the audible band and let designers use smaller filter inductors, reducing amplifier size and weight. The 650 V rating of the CGD65B130SH2 covers +/-100 V audio rails with margin, and the 8-DFN (5x6) footprint allows four devices to be paralleled on a single PCB for higher-power multi-channel amplifiers.

Key Differentiators
- ICeGaN® integrated gate driver and current sense eliminate external driver ICs (vs Discrete 650 V GaN HEMTs without integrated driver)
- 55 mΩ typical RDS(on) at 650 V in 8-DFN (5x6) (vs Silicon 600 V superjunction MOSFET in TO-220 or similar package)
- Automotive-qualified variant available in same footprint (vs Commercial-grade same-die alternatives)
Design Notes
The 8-DFN (5x6) package has a bottom-side cooling pad that doubles as the primary source terminal. Place at least 8 thermal vias in this pad (0.3 mm drill, 0.6 mm pitch) to a continuous inner-layer copper pour sized for the application's dissipation. The gate-drive loop return must connect directly under the source bond to keep the gate-loop inductance under 5 nH - critical because the CGD65B130SH2's 1.9 nC Qg at 12 V transitions in ~5 ns at moderate drive strengths, generating V = L*di/dt spikes that can false-trigger the gate if loop inductance is too high. Follow the Cambridge GaN Devices reference layout in the application note.
Estimated: at 12 A continuous drain current, 25°C ambient, and worst-case RDS(on) of 350 mΩ (datasheet max), the CGD65B130SH2 dissipates roughly P = I²R = 12² × 0.35 = ~50 W if forced to the datasheet maximum. Real applications run at 50-150 mΩ RDS(on) typical, so dissipation drops to 7-22 W. A 50x50 mm FR4 PCB with 2 oz copper on four layers holds theta_JA near 30 C/W, giving ~210°C junction rise at 7 W - heatsink or thermal via array required above ~3 W dissipation.
The CGD65B130SH2 is enhancement-mode (normally-off) but does not have a silicon-MOSFET-style body diode - it uses GaN's intrinsic channel reverse-conduction. Do not parallel anti-parallel silicon diodes across it as you would a silicon MOSFET; the body diode forward voltage (~1.5 V) is higher than silicon's. For totem-pole PFC dead-time control, schedule the synchronous FET turn-on within 50 ns of turn-off to avoid the high body-diode drop penalty. Also do not exceed 12 V VGS; permanent oxide damage occurs above +15 V VGS, and below 0 V VGS the gate is not robust.
