White Paper: Key considerations, architectural demands, and technical solutions for modern cloud server PSUs.
With global hyperscale data centers scaling at unprecedented rates to accommodate AI workloads, large language models (LLMs), and edge computing nodes, power efficiency is no longer just a green metric—it is the governing factor of Operational Expenditure (OPEX). Contemporary server power supply designs (such as Common Redundant Power Supplies, or CRPS) require efficiency benchmarks matching 80 PLUS Titanium, translating to over 96% peak efficiency under load. MOSFET selection dictates the critical margins between achieving these specifications or suffering energy leakage.
Global procurement offices and hardware engineers face challenges maintaining legacy infrastructure while managing component obsolescence. Acquiring stable, pin-to-pin, electrical-parameter-equivalent MOSFET replacements is critical for sustaining server uptime. Our portfolio offers direct alternative pathways for high-frequency switching stages, synchronous rectification, and load distribution switches.
Mapping high-performance semiconductor components to primary, secondary, and auxiliary server power supply stages.
High voltage lines (600V-650V) call for exceptional ruggedness and low switching dissipation. Planar and Superjunction MOSFETs like the WSR55N65F (650V 55A TO-220F) provide reliability during switching transitions, lowering electromagnetic interference (EMI) and maintaining stability under high-line input fluctuations.
Converting high-frequency AC to DC buses (+12V or +48V architectures) requires extremely low conduction losses. Lower voltage (30V to 100V) N-Channel MOSFETs with high current carrying capabilities, such as the WSD6040DN56 (60V 36A) and WSC60N03 (30V 60A), minimize diode conduction periods and maximize active power transfers.
For smart control modules and telemetry, low-power N-channel and P-channel complementary designs (such as WST02N30 and WSD45P04DN56) offer excellent gate control responses, compact SOT-23 and DFN3X3 form-factors, and low gate thresholds compatible with modern microcontroller GPIO logic levels.

Architecting the future of server power converters through Split-Gate Trench (SGT) architectures.
Traditional trench technologies often struggle to balance structural reliability with the absolute minimisation of $R_{DS(ON)}$. The Split-Gate Trench (SGT) technology deployed in our latest mid-to-low voltage MOSFET ranges (30V to 150V) overcomes this constraint. SGT structures incorporate a shielded gate electrode which drastically reduces the gate-to-drain capacitance ($C_{gd}$). This translates directly to shorter transit times, allowing server switching designs to operate at elevated switching frequencies without a corresponding rise in switching energy loss.
By lowering the Figure of Merit ($FOM = R_{DS(ON)} \times Q_g$), engineers can reduce the thermal footprint of their synchronous rectification stages by up to 25%. This optimization allows for denser layouts and smaller heatsinks within modular server power architectures.
| Technology Type | Voltage Coverage | Key Benefits | Target Server PSU Applications |
|---|---|---|---|
| Split-Gate Trench (SGT) | 30V - 150V | Ultra-low $R_{DS(ON)}$, minimized FOM ($Q_g \times R_{DS(ON)}$) | Secondary Synchronous Rectification (+12V/+48V rails) |
| Superjunction (SJ) | 600V - 650V | Fast body diode recovery, high dV/dt immunity | Primary Boost PFC, LLC resonant tank stages |
| Advanced Planar | 150V - 500V | Excellent avalanche ruggedness (EAS), robust thermal profile | Auxiliary switching power supplies, bias lines |
| Complementary Pair (N+P) | 20V - 40V | Compact packaging, simplified logic-level switching | DC-DC step-down converters, system board telemetry |
