MALVERN, Pa. — April 7, 2021 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the SQJA81EP, the world’s most advanced p-channel 80 V TrenchFET® MOSFET qualified to AEC-Q101. The new Vishay Siliconix SQJA81EP has an excellent 80 V p-channel on-resistance for improved power density and energy efficiency in automotive applications. The SQJA81EP is housed in a small 5.13 mm x 6.15 mm PowerPAK® SO-8L monolithic package with a Eurowing lead structure, with a maximum on-resistance of only 17.3 mW / typ. 14.3 mW at 10 V.
The recently released automotive-grade MOSFETs have 28 % lower on-resistance than the closest DPAK-packaged competitor, 31 % lower than previous-generation solutions, and a 50 % smaller footprint, helping to reduce on-power dissipation and save energy , while increasing the power density to improve the output. The excellent gate charge of the SQJA81EP is only 52 nC at 10 V, reducing gate drive losses, and the product of gate charge and on-resistance, the MOSFET figure of merit (FOM) for power conversion applications, is at an industry-leading level.
The device operates at high temperatures of +175 °C and meets the ruggedness and reliability requirements of automotive applications such as reverse polarity protection, battery management, high-side load switching, and LED lighting. In addition, the SQJA81EP gull-wing lead structure also helps improve automatic optical inspection (AOI) capabilities, eliminate mechanical stress, and improve board-level reliability.
The device’s 80 V voltage rating meets the safety margins required for many common input voltage rails in 12 V, 24 V, and 48 V systems. MOSFETs increase power density, thereby reducing the number of components that need to be paralleled and saving PCB space. In addition, as a p-channel device, the SQJA81EP simplifies gate drive design, eliminating the need to configure the charge pump required for n-channel devices. The MOSFETs are packaged in lead (Pb) free, halogen free, RoHS compliant, 100 % Rg and UIS tested.
Samples and production quantities of the SQJA81EP are available now, with lead times of 14 weeks.
