BSS123W Description

Short technical summary and product information.

The BSS123W is a 100V N-Channel enhancement-mode MOSFET designed for low-power switching applications. It features a drain-source on-resistance of 3.5 to 6 ohms at VGS=10V and 170mA, with a gate threshold voltage of 1V to 2.8V. The device is housed in a compact SOT-323 surface-mount package, making it suitable for space-constrained designs. It offers fast switching with typical rise and fall times of 8ns and 16ns respectively. Typical applications include small servo motor controls, power MOSFET gate drivers, and general purpose switching.
