New Product Launch | Lonten DFN5*6 clip for SGT MOSFET, specially designed for commercial drone electric drives

Lonten has officially launched the LSGN04R008FHB N channel power MOSFET, based on advanced shielded gate trench (SGT) technology. It features a 40V withstand voltage, 384A continuous current, and an ultra-low on-resistance of 0.85mΩ as its core performance. Paired with a DFN5×6 clip package, it precisely targets commercial drone ESC (ESC), energy storage BMS, and high-frequency power conversion scenarios.

Especially in response to the stringent requirements of commercial drone power systems for high power density, vibration resistance, reliability, and transient large current response, this device achieves a high-quality balance of current loading, thermal management, switching speed, and robustness in a compact size, providing a reliable power solution for electric drive upgrades in commercial drones.

01 Electrical Performance: Facing the extreme operating conditions of commercial drones

Ultra-low conduction loss, more stable under high-temperature conditions: at VGS=10V, the maximum on-resistance is only 0.85mΩ, with typical values as low as 0.74mΩ; at 150°C junction temperature, the typical value is only 1.3mΩ. When commercial drones hover for long periods or fly at full speed, ESCs maintain high current operation. This feature can significantly reduce conduction voltage drop and heat generation, lessen the heat dissipation burden, and extend flight range.

Ultra-high current load, stronger shock resistance: continuous drain current reaches 384A, pulse peak value reaches 1536A, confidently handling transient shocks such as sudden acceleration, emergency stops, and wind change loads in commercial drones; The single-pulse avalanche energy (EAS) reaches 369 mJ. 100% avalanche testing for the entire batch ensures device safety during motor stalling or abnormal back EMF and avoiding the risk of downtime during downtime.

Excellent high-frequency characteristics, more efficient high-frequency drive: optimized parasitic capacitance balances with gate charge, enabling fast switching speed, strong dv/dt tolerance, and low high-frequency switching losses. Commercial drone ESCs often operate at frequencies of tens of kHz or even higher. This device can significantly reduce switching losses, improve overall power efficiency, and respond more quickly.

02 Packaging Technology Advantage: Designed for commercial drone vibration and compact spaces

Cu Clip Packaging internal structure

LSGN04R008FHB uses DFN5×6 (Cu Clip) packaging, replacing traditional bonding wires with an integrated copper bridge, which is especially advantageous in commercial drone applications:

Copper clamp vibration-resistant structure ensures more reliable high-frequency vibration: no bonding wires or solder joint detachment risks. The integrated copper clamp structure has extremely strong resistance to mechanical vibration and impact, excellently adapting to commercial drone high-frequency vibrations, intense maneuvers, and landing impacts, significantly reducing ESC failure rates.

Low parasitic inductance, purer high-frequency PWM waveforms: The copper clamp directly connects the chip's active region to the pins, greatly reducing parasitic inductance and resistance in the power circuit, suppressing high-frequency switching spikes and EMI, resulting in cleaner waveforms in commercial drone ESCs under high-frequency PWM and smoother motor operation.

Double-sided cooling design for superior power density: exposed drain pads at the bottom and copper clips on top for efficient double-sided heat dissipation; The 5×6mm ultra-compact size can carry 384A of high current, with unit area current capability superior to traditional packages of the same size, helping to miniaturize and lightweight designs for commercial drone ESCs.

Large current cross-sectional area, better resistance to current shocks: The copper sandwich area is much larger than the bonding wire, capable of withstanding continuous high currents and repeated pulse shocks without fuse risks, confidently handling extreme current fluctuations such as sudden turns, hovering, and full load climbs in commercial drones.

Standard small package, more flexible parallel board layout: Standard small packages support high-density board layout and multi-transistor parallel connection, making it easier for ESC manufacturers to optimize BOM costs and PCB area for more compact power modules.

03 Typical Application Scenarios: Meeting the diverse needs of commercial drones

Commercial Drone ESC (ESC) — Primary application, highly effective vibration resistance, small size, large current, enhancing power system stability and range.

Commercial drone power management system -- auxiliary BMS or high-voltage conversion stage, ensuring safe battery charging and discharging.

Synchronous Rectification (SR) and High-Frequency DC-DC Conversion -- Compatible with commercial drone onboard power modules.

It is also suitable for energy storage BMS, PD fast charging, industrial motor drives, and other general high-frequency, high-power applications.
