onsemi BSS84 is a high density cell P-Channel Enhancement Mode MOSFET semiconductor device designed for surface mount applications. With a package type of SOT-23 and 3 pins, it offers efficient voltage controlled switching and high saturation current achieved through ON Semiconductor’s proprietary DMOS technology. This technology minimizes on-state resistance for rugged and reliable performance, making it suitable for fast switching tasks.
The BSS84 MOSFET supports a maximum drain-source voltage of 50 V and a continuous drain current of 130 mA, with maximum power dissipation rated at 250 mW. Thanks to its compact package dimensions (length 3 mm, width 1.3 mm, height 1 mm), it is ideal for space-constrained printed circuit boards in industrial, automotive, and commercial electronic applications.
This device supports a wide temperature range from -65°C minimum to 150°C maximum operating temperature, complying with demanding automotive standards such as AEC-Q100, AEC-Q101, and AEC-Q200. Its maximum gate-source voltage tolerance of ±20 V ensures robust control and operational reliability.
Applications include load switching, DC/DC converter circuits, battery protection systems, power management control, and DC motor control. The MOSFET features a forward voltage of -1.2 V and a typical gate charge of 0.9 nC at the gate-source voltage, reflecting efficient switching performance.
