Alpha and Omega Semiconductor Limited (AOS), a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs, and modules, announced the release of its automotive TO-Leadless (TOLL) package for the company’s automotive grade 80V and 100V MOSFETs. AOS’s TOLL package is developed to optimize the company’s power semiconductors as essential components in the evolution of e-mobility such as 2- and 3-wheel and other light vehicles. This new package helps designers meet the ongoing trend to electrify vehicles with the latest battery technology to meet clean energy zero-emission goals. These capabilities make AOS 80V and 100V MOSFETs ideally suited for automotive BLDC motor and battery management applications for e-mobility.
The AOS automotive TOLL package is designed to achieve the highest current capability using AOS’s innovative approach which utilizes advanced clip technology to achieve a high in-rush current rating. In addition, AOS TOLL packaging with clip technology offers a very low package resistance and inductance, enabling improved EMI performance compared to other TOLL packages utilizing standard wire-bonding technology. With the combination of low ohmic and high current capability, utilizing AOS TOLL packaging also allows designers to reduce the number of parallel MOSFETs in high current applications. This, in turn, helps to enable higher power density requirements without compromising reliability in applications where robustness and reliability are key design objectives.
Providing a more compact solution for space-constrained designs, the AOTL66810Q (80V) and AOTL66912Q (100V) have a 30 percent smaller footprint compared to a TO-263 (D2PAK) package. These new devices in TOLL packaging are qualified to AEC-Q101, PPAP capable, and are manufactured in IATF 16949 certified facilities making them ideally suited for demanding application requirements in e-mobility. AOS TOLL devices are also compatible with automated optical inspection (AOI) manufacturing requirements.
“Using the AOS Automotive TOLL package with clip technology offers significant performance improvements in a robust package. The advanced technologies in our AOTL66810Q and AOTL66912Q MOSFETs will help simplify new designs allowing them to reduce the number of devices in parallel while providing the necessary higher current capability to enable overall system cost savings,” said Peter H. Wilson, Marketing Sr. Director of MOSFET product line at AOS.
