Overview
The BSS84 is a P-channel enhancement-mode field-effect transistor (FET) produced by onsemi using proprietary high cell density DMOS technology. This technology minimizes on-state resistance, providing rugged and reliable performance along with fast switching capabilities. The BSS84 is suitable for a wide range of applications requiring up to 0.13 A DC and can deliver current up to 0.52 A, making it particularly useful for low-voltage applications that need a low-current high-side switch.
