Overview
The BSS138 is an N-Channel enhancement mode Field Effect Transistor (FET) produced by onsemi using their proprietary, high cell density, DMOS technology. This technology enables the BSS138 to achieve low on-state resistance while maintaining rugged, reliable, and fast switching performance. The device is optimized for low voltage, low current applications and is suitable for small servo motor control, power MOSFET gate drivers, and other switching applications. It features a compact industry-standard SOT-23 surface-mount package and is Pb-free and Halogen-free, aligning with current environmental standards for electronic components.
