Small Signal MOSFET

BSS138Active

The BSS138 is a N-channel enhancement-mode MOSFET designed for low-voltage, low-power applications. It is widely used in switching circuits, signal amplification, and logic-level conversion due to its small size, low on-resistance, and compatibility with low-voltage control signals.
