The BSS138W is an N-Channel logic level enhancement mode field effect transistor from On Semiconductor. Designed for low voltage and low current applications, it offers a drain-source voltage rating of 50V and a continuous drain current of 210mA. The device features low on-resistance: 3.5 Ohm maximum at VGS=10V and 6.0 Ohm maximum at VGS=4.5V, enabling efficient switching. Gate threshold voltage ranges from 0.8V to 1.5V, making it suitable for logic level drive.
With low gate charge (1.1nC max) and input capacitance (38pF max), the BSS138W provides fast switching performance. Power dissipation is 340mW at 25°C ambient, and the operating junction temperature range is -55°C to 150°C. The device is packaged in a compact SOT-323 surface mount package (also referred to as SC-70), which is ideal for space-constrained designs.
Applications include small servo motor control, power MOSFET gate drivers, and other low-voltage switching circuits. The BSS138W is Pb-Free and Halide Free per the datasheet, and is RoHS compliant per manufacturer data.
