BSS123L Description

Short technical summary and product information.

The BSS123L is an N-Channel enhancement-mode MOSFET manufactured by On Semiconductor. It is designed for low-power switching and amplification applications in compact surface-mount designs. The device features a maximum drain-to-source voltage of 100V and a maximum drain current of 170mA at ambient temperature, making it suitable for small-signal switching tasks.

 

Key electrical characteristics include a maximum drain-source on-resistance of 6 ohms at a gate-source voltage of 10V and drain current of 170mA, and a maximum gate threshold voltage of 2V at 1mA drain current. The device supports gate drive voltages of 4.5V and 10V, allowing flexible logic-level or standard drive configurations. Maximum power dissipation is 360mW at ambient temperature.

 

The BSS123L is housed in a TO-236-3 (SC-59, SOT-23-3) surface-mount package, ideal for space-constrained PCB layouts. It operates over a junction temperature range of -55°C to 150°C, supporting use in a wide range of environments. The MOSFET uses metal-oxide semiconductor technology and is suitable for general-purpose switching in low-current circuits.
