New advanced HV MOSFETs optimized to meet the
high efficiency needs in LLC, PSFB Converters and H-4 and
Cyclo-Inverters of Solar/ESS applications
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a
designer, developer, and global supplier of a broad range of
discrete power devices, wide band gap power devices, power
management ICs, and modules, today announced the release of two
αMOS5™ 600V FRD Super Junction MOSFETs. αMOS5™ is AOS’s market and
application-proven high voltage MOSFET platform, designed to meet
the high efficiency and high-density needs of servers,
workstations, telecom rectifiers, solar Inverters, EV charging,
motor drives and industrial power applications.

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.
Technical Highlights
- Rugged, fast recovery diode (FRD) with reduced Qrr for
demanding use cases
- Engineered for both hard and soft switching topologies with
ultra-low switching loss
- Strong UIS and SOA capabilities
- Engineered to prevent self turn-on
- Suitable for LLC, PSFB, CrCM Totem-Pole, Multi-level NPC and
CrCM H-4/Cyclo Inverter applications
