BSS138LT1 N-Channel Power MOSFET 200mA 50V (SOT−23) delivers efficient switching and low-power control for compact electronic designs. Engineers and hobbyists use this MOSFET in battery-powered circuits, load switches, and signal amplification due to its high-speed performance and miniature footprint.

Key Features:
  • Low Threshold Voltage: Enables control with minimal gate drive power.
  • Fast Switching Speed: Reduces power loss in high-frequency applications.
  • SOT-23 Package: Saves space on PCBs for portable and IoT devices.
  • Low On-Resistance: Maximizes efficiency at 200mA loads.
  • ESD Protection: Guards against electrostatic discharge damage.
Technical Specifications:
  • Drain-Source Voltage (VDS): 50V
  • Continuous Drain Current (ID): 200mA
  • On-Resistance (RDS(on)): 3.5Ω (max) at VGS=4.5V
  • Gate-Source Voltage (VGS): ±12V (max)
  • Power Dissipation (PD): 225mW
Mechanical Specifications:
  • Package Type: SOT-23 (Surface-Mount)
  • Termination: Tin-plated leads (Pb-free)
  • Moisture Sensitivity: Level 1 (MSL1)
Dimensions:
  • Package Length: 2.9mm (max)
  • Package Width: 1.3mm (max)
  • Lead Pitch: 0.95mm
Pinout and Wiring:
  • Pin 1 (Gate): Controls switching via voltage input.
  • Pin 2 (Source): Connects to ground/common return.
  • Pin 3 (Drain): Output to load; handles up to 50V.
  • For basic switching, apply voltage to Pin 1 (Gate) relative to Pin 2 (Source).
Datasheet Reference:
  • Search “BSS138LT1 datasheet PDF” for detailed curves, test circuits, and thermal guidelines.
Applications:
  • Battery Management: Protects circuits from reverse polarity or overcurrent.
  • Signal Switching: Routes low-power analog/digital signals in multiplexers.
  • Portable Electronics: Powers LED drivers, sensors, and wearables efficiently.
  • Automotive Modules: Supports 12V/24V system controls (within specs).
Equivalent Models:
  • 2N7002: Similar N-Channel MOSFET (60V, 115mA).
  • DMG2302UX: Lower RDS(on) alternative (20V, 2.7A).
  • NDS355AN: Higher current (1.7A) SOT-23 option.
Package Includes:
  • 1 x BSS138LT1 N-Channel MOSFET (SOT-23)
