BSS123TA Description

Short technical summary and product information.

The BSS123TA is an N-Channel enhancement mode field effect transistor from Diodes Incorporated, manufactured using advanced trench technology to minimize on-state resistance while providing rugged, reliable, and fast switching performance. Key specifications include a drain-source voltage rating of 100V, continuous drain current of 170mA at 25°C, and a maximum on-resistance of 6 Ohms at Vgs=10V. The device features low input capacitance of 20pF and a gate threshold voltage of 2V max, making it suitable for logic-level drive. It is designed for low-voltage, low-current applications such as small servo motor controls, power MOSFET gate drivers, and general switching circuits. The MOSFET is housed in a surface mount SOT23-3 package (also known as TO-236-3 or SC-59) and operates over a temperature range of -55°C to 150°C. It is fully RoHS3 compliant, lead-free with matte tin finish, and halogen and antimony free (Green Device). Moisture sensitivity level is 1 per J-STD-020.
