SUNNYVALE, USA: Alpha & Omega Semiconductor, Inc. (AOS) today announced extensions to their high performance SDMOS TM family with new 80V and 100V MOSFETs. The AOT410 and AOT480 are ideal choices for high current synchronous rectifiers in server, ATX, UPS and other high efficiency AC-DC power supplies.
The new devices are fabricated on AOS’ proprietary SDMOS trench technology. The low on-resistance and Soft Diode characteristics of the MOSFETs are tuned to deliver the optimal combination of high efficiency and low noise operation.
“By considering all the major power loss mechanisms we were able to balance the characteristics of the AOT410 and AOT480 to deliver exceptional performance in power conversion applications. The products offer the advantage of a low Qrr, soft recovery body diode to improve dead-time operation and reduce noise in hard switched topologies,” said David Grey, Marketing Director for AOS’ MOSFET products.
Both devices are housed in the TO220 package and are available immediately in production quantities. The unit price of 1,000 pieces is as follows: AOT480L at $1.72, and AOT410L at $1.76.
