The Si3801DV is a low on-resistance p-channel power
MOSFET providing 12-V bi-directional blocking and
low-resistance bi-directional conduction. The Si3801DV was
realized by integrating two rugged, p-channel, high density
Trench process, vertical MOSFETs in a common drain area.
This yields exactly the same “reverse blocking” results as
externally connecting the drains of a dual MOSFET, but
without the wasted separation between two die and the area
lost to drain connections that can be avoided by connecting
them internally. Additional space is saved by tying the two
gates common. This allows the Si3801DV to replace a larger
dual MOSFET package with a single smaller footprint, lower
profile, TSOP-6 package.
