BSS138-F085 Description

Short technical summary and product information.

The BSS138-F085 is an N-Channel enhancement-mode MOSFET manufactured by On Semiconductor. It features a drain-to-source voltage (Vdss) of 50V and a continuous drain current (Id) of 220mA at ambient temperature. The device is built using Metal Oxide semiconductor (MOSFET) technology.

 

Key electrical characteristics include a maximum drain-source on-resistance (Rds(on)) of 3.5 Ohms at Vgs = 10V and Id = 220mA, a gate threshold voltage (Vgs(th)) of 1.5V maximum at Id = 1mA, and a maximum gate charge (Qg) of 2.4 nC at Vgs = 10V. Input capacitance (Ciss) is 27 pF at Vds = 25V. The device can handle a maximum power dissipation of 360mW at ambient temperature.

 

The MOSFET operates over a junction temperature range of -55°C to 150°C. It is designed for surface-mount assembly, available in TO-236-3, SC-59, and SOT-23-3 packages, with the supplier device package designated as SOT-23-3. The drive voltage range is 4.5V to 10V for optimal Rds(on) performance.
