The first product released – AOK040A60 is a 600V 40mOhm αMOS5
low ohmic device with the industry-standard TO-247 package tailored
to address the thermal challenges of today’s high-power AC/DC,
DC/DC, and Inverter stages. As the EU ERP Lot9 regulation pushes
the efficiency of single PSUs to Titanium level, AOS αMOS5 600V low
ohmic family provides an ideal solution for single, interleaved,
dual boost, totem-pole, and Vienna PFCs, as well as other
hard-switching topologies. The 40mOhm product, followed by our
upcoming 31mOhm, 65mOhm, and 80mOhm products, will provide
customers with multiple choices to deal with different power
ratings and efficiency requirements. The optimized capacitance of
AOK040A60 will provide customers the best hard and soft switching
performances, with fast turn-on/turn-off behaviors while avoiding
the risks of self-turn-on or shoot-through, thanks to AOS’s silicon
design and process know-how.
The second product released – AOK042A60FD is a 600V 42mOhm FRD
(Fast Body Diode) device, designed to handle the repetitive hard
commutation scenario, where the MOSFET’s freewheeling body diode is
reversely recovered in HB (half-bridge) or FB (full bridge)
topologies. The αMOS5 600V FRD solution will further increase the
system reliability as the right-fit solution for HB/FB topologies
where hard switching happens during abnormal operations, such as
short-circuit or start-up transients. The low Qrr of AOK042A60FD
will help significantly reduce the losses during reverse
recovery.
Besides Server and Telecom power supplies, the AOK040A60,
AOK042A60FD and their derivatives will also target the demanding EV
DC charging and Solar Inverter applications.
The 600V αMOS5 family will have a portfolio expansion including
more low ohmic and FRD products coming Q1’2022. As with most of our
αMOS5 products, these new devices will also be fabricated in 300mm
facilities, providing better supply elasticity during the global
power semiconductor shortage.
“AOS’s commitment to high power SMPS applications is getting
stronger. αMOS5 600V low ohmic and FRD solutions will make it
possible for Server Power and Solar inverter designs to achieve
higher power ratings while keeping the same form factors. Our
devices’ superior efficiency will reduce customers’ TCO (total cost
of ownership) by minimizing electricity, cooling and ventilation
bills. Additionally, today’s EV charging stations have reached more
than 50kW per module. As power density becomes an increasingly
critical differentiation factor, lower ohmic devices provide better
conduction loss, thus lower thermal stress to the system. With the
release of our 600V low ohmic and FRD family, we will offer the
industry’s best granularity of Rdsons and packages, covering a wide
range of power ratings and densities. AOS’s market-proven αMOS5
600V low ohmic and FRD products are our answers for tomorrow’s
server, telecom, solar, and EV charging applications, satisfying
our customers’ growing demand for performance and reliability,”
said Richard Zhang, Director of High Voltage MOSFET Product Line at
AOS.
