onsemi N-Channel MOSFET, 200 mA, 50 V Enhancement, 3-Pin SOT-23 Package BSS138LT1G

The onsemi BSS138LT1G is a high-quality N-Channel enhancement mode MOSFET designed for use in power management and switching applications. This compact 3-pin SOT-23 package is ideal for surface-mount technology (SMT) designs, providing efficient space utilization on printed circuit boards. It supports a continuous drain current of up to 200 mA and withstands a maximum drain-source voltage of 50 V, making it suitable for low power electronic circuits.

This MOSFET exhibits a maximum drain-source resistance of 3.5 Ω, ensuring minimal conduction losses and enhanced switching precision. Its power dissipation rating of 225 mW accommodates moderate power loads while maintaining reliability across a broad temperature range from -55°C to 150°C, which makes it reliable for industrial and commercial environments.

The typical gate charge of 160 nC at the gate-source voltage supports efficient and fast switching performance, while the gate voltage withstands peaks from -20 V to +20 V, protecting the device against voltage spikes. The physical dimensions (2.9 mm length, 1.3 mm width, and 940 μm height) allow for compact integration into modern electronics.

This device finds applicability across diverse sectors including industrial automation, consumer electronics, telecommunications, and automotive electronics where precise low-power switching is needed.
