Debut of High Performance HV MOSFET aMOS5 Platform

Alpha and Omega Semiconductor Limited (AOS), a designer, developer and global supplier of a broad range of power semiconductors and power ICs, today announced the release of AOTF190A60L, the first product in the new aMOS5TM HV MOSFET platform.  This device provides high-efficiency performance in an easy-to-use solution optimized for server power supplies, high-end computers, charging stations and other high-performance applications.  aMOS5TM reduces the on-resistance ‟RDS x A” per unit area by 30% versus the previous generation, enabling lower conduction losses in the application.  It also enables future HV product offerings to fulfill the market trend of higher power density in a new, smaller and more efficient package.

Additionally, aMOS5TM significantly improves switching performance compared to major competitors; AOTF190A60L offers lower total gate charge with much shorter switching plateau time, which helps reduce switching losses.  The new product is packaged in a full-molded TO-220F and has a maximum RDS(ON) of 190mohm.

aMOS5TM was engineered to provide superior  EMI performance by optimizing parasitic parameter behavior.  The following waveform comparison shows how the EMI is controlled, with a suppressed reverse recovery current (Irr) and a much smoother voltage ramp up during the device turn off.

‟The switched-mode power supply is the energy heart in modern IT equipment. The demand for higher power conversion efficiency is driven by the huge amount of electricity consumed by power supplies around the world. High performance converting topologies such as LLC have become the standard solution for most AC/DC converters used by servers inside data center and telecom infrastructure. MOSFET performance is critical to achieving the highest efficiency provided by the power converters. We are glad to announce the release of the AOTF190A60L, based on our latest high voltage MOSFET platform – aMOS5TM. The new technology platform targets high efficiency solutions in both PFC and LLC applications,” said Simon Lu, Marketing Director of HV MOSFET product line at AOS.

Pricing and Availability

The AOTF190A60L is immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 1,000 pieces is $2.24.
