Super Junction Mosfet Products
Superjunction MOSFETs are advanced semiconductor devices designed to overcome the limitations of traditional planar MOSFETs. By introducing a unique multi-layer structure, these devices achieve high efficiency, lower conduction losses, and reduced switching losses. Unlike standard MOSFETs, which struggle with high-voltage applications due to increasing resistance, Superjunction MOSFETs use alternating P- and N-type layers, optimizing their electrical and thermal properties.

05
The innovation behind Superjunction MOSFETs lies in their vertical structure. Traditional MOSFETs rely on horizontal current flow, causing higher resistance in high-voltage scenarios. Superjunction MOSFETs overcome this with a vertically aligned drift region made of alternating P- and N-doped layers.
This configuration reduces the overall resistance without increasing the device size. When the MOSFET is in the "on" state, electrons flow vertically through the drift region with minimal resistance. In the "off" state, the layers help block high voltages, ensuring reliable performance.
Performance Comparison of Super Junction Mosfet Products
On-Resistance and Efficiency
●D-MOS: The on-resistance in conventional D-MOS devices increases sharply with voltage. The need for a thick, lightly doped drift region leads to higher conduction losses.
●Super-Junction MOSFETS: Thanks to the charge compensation technique, SJ-MOSFETs have a much lower on-resistance. This efficiency improvement means that for the same voltage rating, an SJ-MOSFET will dissipate less power as heat, which is critical for applications like power converters and motor drives.
Switching Speed
●Lower Parasitics: SJ-MOSFETs benefit from reduced input and output capacitances due to the optimized drift region structure. This reduction allows for faster rise and fall times, enabling more efficient high-frequency operation.
●Improved dv/dt: The more uniform electric field in SJ devices contributes to improved switching characteristics with lower energy loss during transitions.
Breakdown Voltage
●Uniform Electric Field Distribution: In D-MOS devices, the electric field concentrates at a single junction, which can limit the breakdown voltage. In contrast, the SJ structure distributes the electric field evenly across the drift region, allowing for higher breakdown voltages without sacrificing on-resistance.
Structural Differences of Super Junction Mosfet Products
D-MOS Structure
●Single-Layer Drift Region: In a conventional D-MOS, the drift region is uniformly doped at a low level to support the desired breakdown voltage.
●Limitation Due to the “Silicon Limit”: To maintain high voltage capability, the drift region must be thicker and less heavily doped, which increases the device’s resistance and switching losses.
Super-Junction Structure
●Alternating P/N Columns: The key innovation in SJ-MOSFETs is the incorporation of multiple alternating p-type and n-type regions in the drift area. These columns are precisely engineered to balance charge (charge compensation), resulting in a nearly uniform electric field.
●Optimized Drift Region: Because the electric field is spread uniformly, designers can use a higher doping concentration in the drift region without compromising the breakdown voltage. This design directly translates into lower on-resistance.
●Enhanced Capacitance Characteristics: The super-junction structure also results in reduced parasitic capacitance, which benefits switching performance by minimizing energy losses during transitions.
Design Considerations for Superjunction MOSFETs
