NEXPERIA BSS84AKW P-Channel Power MOSFET, 50V 150mA, SOT-323

The NEXPERIA BSS84AKW is a high-performance P-channel enhancement-mode field-effect transistor (FET) housed in a compact SOT-323 surface-mount package. Manufactured using advanced Trench MOSFET technology, this component is designed for efficient power control in space-constrained applications. Its logic-level compatibility makes it an ideal choice for direct interfacing with microcontrollers and other low-voltage logic circuits, simplifying design and reducing component count. The device incorporates robust ESD protection rated up to 1 kV, significantly enhancing its reliability and resilience in handling and operational environments.

A key attribute of the BSS84AKW is its very fast switching capability, which is essential for minimising power loss and improving efficiency in high-frequency applications. The MOSFET is AEC-Q101 qualified, meeting the stringent reliability standards required for automotive electronics, and can operate across an extensive junction temperature range from -55°C to 150°C. This makes it suitable for use in demanding environments where temperature extremes are common. With a continuous drain current rating of 150 mA and a low drain-source on-state resistance (Rds(on)) of just 7.5 ohms, it ensures minimal voltage drop and power dissipation during operation.
