Le blog de l'entreprise Mingjiada Electronics Supply and Procurement: Oriental SFS04R013 – An N-Channel Power MOSFET for Use in Server Power Supplies

In this era of rapid development in high-performance computing and data centres, the efficiency and reliability of power management systems have become a key focus for the industry. As a key link in the electronic components supply chain, Shenzhen Mingjiada Electronics Co., Ltd. not only maintains a long-term stock of Oriental Semi’s flagship product—the SFGMOS series MOSFET SFS04R013—but also actively purchases this model and related idle stock at premium prices from the market, committed to providing customers with a one-stop solution ranging from supply to recycling.

Product Spotlight: Oriental Semi SFS04R013 MOSFET

The SFS04R013 is a high-performance N-channel power MOSFET from Oriental Semi’s SFGMOS series. This device utilises advanced semi-floating-gate structure technology, combining the advantages of both traditional planar structures and SGT structures to deliver superior process stability and reliability.

Key Specifications and Advantages:

Low On-Resistance: The SFS04R013 has a maximum on-resistance as low as 1.1 mΩ (at VGS = 10 V), significantly reducing conduction losses during high-current transmission.

High voltage rating and high current capacity: With a drain-source voltage (VDS) of 40 V, a pulse drain current (ID, pulse) of up to 600 A and a continuous drain current of 200 A, it is suitable for high-power-density designs.

Fast switching: Featuring extremely low switching losses and fast switching characteristics, combined with low gate charge (Qg), it effectively improves system efficiency.

Package Type: Utilises a compact PDFN5×6 package, facilitating multi-device parallel operation and high-power-density layouts.

Core Application Scenarios: Server Power Supplies and Synchronous Rectification

The SFS04R013 has been specifically optimised for low-drive-voltage synchronous rectification applications; its low on-resistance and fast switching characteristics enable it to perform exceptionally well in the following scenarios:

1. Server Power Supplies

In a teardown analysis of the Megamit 1600W CRPS server power supply, the SFS04R013UGF was extensively utilised in key positions such as the LLC secondary-side synchronous rectification, main output ORing/output control, and standby output control. For high-current 12V outputs in the 100-ampere range, the SFS04R013, with its milliohm-level on-resistance, effectively reduces losses in the synchronous rectification and output paths, helping the power supply module achieve higher conversion efficiency and lower temperature rise.

2. Synchronous Rectification and DC-DC Conversion

This device is ideally suited for isolated DC/DC converters and synchronous rectification circuits. Its fast switching and soft recovery characteristics help to reduce switching noise and improve the system’s EMI performance.

3. Motor Drivers and Inverters

In addition to the power supply sector, the SFS04R013 can also be used in motor control and inverter systems, providing efficient power transmission control.

4. Automotive Electronics

Notably, the SFS04R013UGF has been certified to AEC-Q101 and is suitable for automotive systems such as on-board DC-DC converters, EPS (Electric Power Steering) and EPB (Electronic Parking Brake), meeting the automotive industry’s stringent reliability requirements.
