Overview of BSS138W by onsemi
The BSS138W is an N-Channel Logic Level Enhancement Mode Field Effect Transistor (FET) characterized by a drain-source voltage of 50V, a continuous drain current of 210mA, and a low drain-source on resistance of 3.5 Ohms when tested at 10V. This makes it a highly efficient component for low-power switching applications. Packaged in a compact SOT-323-3, this surface-mount device is designed for high-density PCB applications. The gate-source threshold voltage maxes out at 1.3V, allowing for logic-level control which makes it compatible with a wide range of microcontrollers and logic devices.
The part comes with several notable features listed under the Part Data Attributes on findchips.com. These include being RoHS compliant and having a moisture sensitivity level of 1, which allows it to withstand ambient conditions with minimal precautionary requirements against moisture-induced damage. The low feedback capacitance (Crss) of 3.5pF minimizes undesirable cross-talk, improving performance in high-speed switching applications. Its maximum power dissipation is 0.34W, pointing towards efficient thermal management in operational conditions. Additionally, the BSS138W is described with an “Ultra-Low Resistance” feature, emphasizing its efficiency in applications where power conservation is critical.
Its active status in the part lifecycle indicates ongoing production and availability, although the factory lead time, as of the current writing, stands at 52 weeks. This suggests planning for procurement should account for potential delays.
