The BSS138-7-F N-Channel Logic-Level MOSFET is a low-voltage, enhancement-mode MOSFET optimized for logic-level gate drive applications. With a low gate threshold voltage and low R<sub>DS(on)</sub> at low V<sub>GS</sub>, it enables efficient switching directly from microcontrollers and digital logic circuits.
Housed in a compact SOT-23 package, the device provides fast switching characteristics, low gate charge, and minimal power dissipation, making it ideal for bidirectional level shifting, signal switching, load control, and interface protection. It is commonly used in I²C, UART, SPI level translators, as well as in embedded systems, IoT modules, sensor interfaces, and industrial control electronics where space, efficiency, and reliability are essential.
