The BSS138BK is an N-channel 60V 400mA small signal MOSFET in an SOT-23 package, designed for switching circuits, low-side load switches, and relay drivers. It features a maximum R_DS(on) of 0.68Ω at 10V gate-source voltage and supports ultra-low voltage drive down to 2.5V. The device includes ESD protection up to 2kV (HBM), is RoHS compliant, and halogen-free. Continuous drain current is rated at 400mA with a power dissipation of 350mW. The junction temperature range is -55°C to +150°C. Thermal resistance junction-to-ambient is 357°C/W on a ceramic board and 625°C/W on an FR4 board. It operates with gate-source voltage up to ±20V and has a typical forward body diode voltage of 1.2V at 290mA.
Single Nch 60V 400mA MOSFET and ESD protection diode are included in the industry’s favorite SOT-23 package. Ideal for switching circuit and low-side load switch, relay driver applications.
