The BSS138K is an N-Channel logic level enhancement mode field effect transistor manufactured by On Semiconductor. Designed for low-voltage switching applications, it offers a maximum drain-source voltage (Vdss) of 50V and a continuous drain current of 220mA at 25°C ambient temperature, with a pulsed drain current rating of 0.88A.
Key electrical characteristics include a maximum drain-source on-resistance (Rds(on)) of 1.6 Ohm at VGS=5V and ID=50mA, ensuring efficient switching with low conduction losses. The gate threshold voltage (Vgs(th)) ranges from 0.6V to 1.2V, allowing direct interfacing with low-voltage logic circuits. The device also features low input capacitance (Ciss typical 58pF) and a maximum total gate charge of 2.4nC at VGS=10V, contributing to fast switching speeds.
The BSS138K is housed in a surface-mount SOT-23-3 package (also known as TO-236-3 or SC-59), making it suitable for compact PCB designs. It is rated for an operating junction temperature range of -55°C to +150°C and has a maximum power dissipation of 350mW when mounted on a standard FR-4 PCB. The device is Pb-Free and RoHS compliant, and it is supplied in tape and reel packaging with 3000 pieces per reel.
