Alpha and Omega Semiconductor Releases αMOS5™ 600V FRD 95mohm and 125mohm Super Junction MOSFET
- The new MOSFETs are tailored for fast switching, ease-of-use, and robustness in mission-critical applications.
- The devices have been tested to survive high di/dt under abnormal system conditions, even at elevated junction temperatures of up to 150°C.
- The turn off energy (Eoff) of the devices are lower than the competition's, contributing to higher efficiency in light or mid-load conditions.
- The unit price in 1,000-piece quantities for the AOK095A60FD (600V 95mohm TO-247) is $3.75, and for the AOTF125A60FDL (600V 125mohm TO-220F) is $3.22, which may be considered relatively high by some potential buyers.
- The lead time for production quantities is 16 weeks, which could be a concern for businesses requiring immediate availability.
The release of Alpha and Omega Semiconductor Limited's new αMOS5™ 600V FRD Super Junction MOSFETs signifies a notable advancement in power semiconductor technology. These devices are engineered to address the critical demands of higher efficiency and density in power conversion systems. The Super Junction MOSFET is a type of power MOSFET that offers reduced on-resistance and lower switching losses compared to conventional MOSFETs, which is crucial for improving the performance of power supply units and inverters.
From an engineering perspective, the robust design of the intrinsic body diode in these MOSFETs is significant. It ensures the device can withstand high di/dt, or rate of change of current, during abnormal system conditions such as short-circuits or start-up transients. This robustness is critical in applications like solar inverters and energy storage systems (ESS) where reliability under various load conditions is paramount. Furthermore, the claim of lower turn off energy (Eoff) compared to competitors, if substantiated, could result in reduced thermal stress and potentially longer device lifespans.
The mention of fast recovery diode (FRD) with reduced Qrr (reverse recovery charge) highlights the focus on minimizing losses during the diode's recovery phase, which is a key factor in high-frequency power applications. The suitability for both hard and soft switching topologies indicates versatility in application, which can be a strong selling point for a wide range of power electronics systems.
Alpha and Omega Semiconductor Limited's introduction of new MOSFETs is strategically positioned to capture growth in the renewable energy and electric vehicle (EV) charging markets. As the demand for more efficient power conversion systems grows, AOS's products could see increased adoption in solar photovoltaic (PV) inverters, energy storage systems and EV charging infrastructure. The emphasis on bi-directional topologies aligns with the trend towards energy storage-ready inverters, which are becoming increasingly important as the integration of high voltage batteries in AC-coupled systems gains traction.
The financial impact of these new products on AOS's revenue stream could be significant, especially given the competitive pricing and the current industry shift towards higher efficiency components. The disclosed unit prices are competitive and if the MOSFETs deliver on their promised performance, they could achieve a strong market penetration. However, investors should monitor the production scale and market acceptance of these MOSFETs, as the 16-week lead time could impact the speed of revenue realization.
In the long-term, AOS's position in the power semiconductor market could be strengthened by these releases, provided they maintain a track record of reliability and performance in the field. This could lead to an improved market share and potentially positive effects on the company's stock valuation.
The immediate availability of the AOK095A60FD and AOTF125A60FDL MOSFETs, with a 16-week lead time, reflects a well-managed supply chain strategy. In the context of recent global supply chain disruptions, a 16-week lead time is reasonable for semiconductor components and indicates that AOS has accounted for potential delays in manufacturing and logistics. It is important for stakeholders to consider the potential impact of supply chain constraints on the ability to meet market demand, especially for components that are critical to the infrastructure of renewable energy and electric vehicle markets.
Supply chain resilience is a key factor in the semiconductor industry and AOS's ability to ensure product availability could provide a competitive advantage. However, it is also crucial to assess the company's capacity to scale up production if demand for their new MOSFETs exceeds expectations. An inability to scale could lead to missed opportunities and allow competitors to fill the gap.

The design of today’s mid-high power switched-mode power supply (SMPS) and solar inverter systems boil down to four major challenges – higher efficiency, higher density, lower system costs, and uncompromised robustness. High Voltage Super Junction MOSFETs are the dominant choice for topologies such as single/interleaved/dual boost/CrCM TP PFCs, LLC, PSFB, multi-level NPC/ANPC and so forth.
αMOS5™ has been the leading High Voltage Super Junction solution tailored for fast switching, ease-of-use and robustness in mission-critical applications. αMOS5™ FRD FETs are engineered with strong intrinsic body diode to handle hard commutation scenarios, when the freewheeling body diode is in reverse recovery due to abnormal operations, such as short-circuit or start-up transients. The two products released, the AOK095A60FD (TO-247) and AOTF125A60FDL (TO-220F), are 600V FRD FETs with 95mohm and 125mohm maximum Rdson, respectively. In tests conducted by AOS engineers, the body diodes of these two FRD FETs have survived high di/dt, under abnormal system conditions, even at elevated junction temperatures of up to 150°C. Additionally, AOS tests have shown that these devices’ turn off energy (Eoff) are noticeably lower than the competition’s, which contributes to higher efficiency in light or mid-load conditions.
“We defined our products for traditional power supplies, as well as DC/DC and DC/AC converters of solar inverters and ESS systems, where bi-directional topologies are needed. As energy storage-ready inverters become the trend and high voltage batteries are utilized increasingly in AC-coupled systems, the AOK095A60FD and AOTF125A60FDL will become industry leading solutions for bi-directional DC/DC and inverter/PFC applications that serve a wide range of power supplies, solar PV inverters, and ESS hybrid converters,” said Richard Zhang, Senior Director of Product Line and Global Power Supply Business at AOS.
