Description
This P-channel enhancement-mode field-effect
transistor is produced using Fairchild’s proprietary,
high cell density, DMOS technology. This very high
density process minimizes on-state resistance and to
provide rugged and reliable performance and fast
switching. The BSS84 can be used, with a minimum
of effort, in most applications requiring up to 0.13 A
DC and can deliver current up to 0.52 A. This product
is particularly suited to low-voltage applications
requiring a low-current high-side switch.
Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only. Values are at T
A
= 25°C unless otherwise noted.

θJA
is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference
is defined as the solder mounting surface of the drain pins. R

is
determined by the user's board design.
