Both the above figures are with 10V drive to the gate.
The device is the SQJA81EP, which comes in a 5.13 x 6.15mm surface-mount PowerPAK SO-8L (PowerPAK) package with gullwing leads – gullwings allow for increased automatic optical inspection capabilities and provide mechanical stress-relief for increased board-level reliability.
“With the lowest on-resistance of any -80V p-channel device, the Vishay Siliconix SQJA81EP increases Power density and efficiency in automotive applications,” according to New Yorker Electronics, which is stocking the part. “on-resistance is 28% lower than the closest competing device in DPAK, while offering a 50% smaller footprint.”
Use is foreseen in reverse polarity protection, battery management, high-side load switching and LED lighting. Unlike with an n-channel MOSFET used on the high-side, no charge pump is needed with a p-channel transistor.
An 80V rating provides some safety margin on 12, 24 and 48V rails.
