BS170 Datasheet. Specs and Replacement
The BS170 is an N-channel enhancement-mode MOSFET designed for low-power switching and amplification applications. It features a high input impedance and fast switching performance due to its MOS gate structure. The device is housed in a TO92 package, making it suitable for compact and through-hole designs. The BS170 typically supports a drain-source voltage up to 60V and a continuous drain current of approximately 500mA, depending on thermal conditions. It offers low gate threshold voltage, allowing direct drive from logic-level signals. Common applications include signal switching, small motor control, LED drivers, general purpose analog and digital circuits.
