The onsemi BSS138LT1G is a single N-channel logic-level MOSFET in a SOT-23 package. It is rated for 50V drain-to-source, 200mA continuous drain current, and 3.5Ω on-resistance, with a 1.5V threshold voltage. The device is RoHS compliant and rated for operation up to 150°C junction temperature.
This logic-level N-channel MOSFET is widely used for low-side switching, level translation, and interfacing between logic families and small loads. Its low threshold lets it be driven directly from microcontroller GPIO, making it a staple in consumer, industrial, and IoT designs for gating power to LEDs, sensors, and small relays.
Fusion’s in-house quality hubs and Prosemi testing facility are fully certified to meet critical industry standards for electronic component inspection and testing.
