Alpha and Omega Semiconductor Limited (AOS) (NASDAQ: AOSL) introduces new highly robust power MOSFET LFPAK 5×6 pacakge offering high reliability, and is available in a wide range of voltages: 40V, 60V, and 100V. It is designed to withstand harsh environments while maintaining MOSFET performance. The new devices are found in a broad range of applications such as industrial, server power, telecommunications, and solar, where high reliability is required.
AOS designs, develops and supplies broad range of discrete power devices, wide band gap power devices, power management ICs, and modules. Its LFPAK packaging enables higher broad-level reliability due to key packaging features such as gull-wing leads, which offer a ruggedized solution for board-level environmental stresses. The gull-wing leads also enable optical inspection during PCB manufacturing.
Further LFPAK’s larger copper clip improves electrical and thermal performance offering several advantages including improved current handling capabilities, reduced on-resistance, and better hear dispersion compared to wire bonding. The large clip also has low parasitic inductance, enabling lower spike voltage in switching applications. These features significantly improve the robustness of the MOSFET, and utilizing AOS’s advanced shielded gate MOSFET Technology (AlphaSGT) enables designers to find an optimized solution to achieve high reliability under the harshest environmental conditions.
“Designers have long trusted AOS power semiconductors in their applications, and LFPAK 5×6 will expand solution capability,” said Peter H. Wilson, Marketing Sr. Director of the MOSFET product line at AOS.
The LFPAK 5×6 family includes several key products, each with distinct technical specifications. The AOLF66412 and AOLF66413 have a VDS of 40V, a VGS of ±20V, and can handle currents of 352A and 374A, respectively, with a maximum RDS(ON) of 1.5mΩ at VGS=10V. The AOLF66417 also operates at 40V and ±20V but with a current capacity of 200A and a maximum RDS(ON) of 2.6mΩ. The AOLF66610 offers a VDS of 60V, VGS of ±20V, 294A current capacity, and an RDS(ON) of 2mΩ. The AOLF66910 supports a higher VDS of 100V, a VGS of ±20V, 187A current capacity, and an RDS(ON) of 4.7mΩ. All devices have a maximum junction temperature of 175°C.
These products are now available in production quantities with a lead time of 14-16 weeks. Pricing per 1,000 units is as follows: $1.15 for AOLF66412, $1.17 for AOLF66413, $0.78 for AOLF66417, $1.65 for AOLF66610, and $2.10 for AOLF66910.
