BSS138 J1 SOT-23 50V 350mA MOSFET

Product Description: BSS138 SOT23 50V 350mA MOSFET

The BSS138 is a high-performance N-Channel MOSFET designed for use in low-voltage switching and signal amplification applications. Packaged in the compact and space-efficient SOT-23 form factor, the BSS138 is ideally suited for low-power circuits, logic-level switching, and small signal amplification. With a drain-source voltage (V_DS) rating of 50V and a continuous drain current (I_D) of up to 350mA, this MOSFET is perfect for small-scale power control and electronic projects requiring efficient switching and low conduction losses.

The BSS138 features a low gate threshold voltage (V_GS(th)), typically around 1.3V, which allows it to switch on with a lower voltage, making it ideal for logic-level switching in 5V or 3.3V circuits. The low R_DS(on) ensures minimal power dissipation during operation, making the BSS138 a highly efficient component for battery-powered systems, power management, and digital logic circuits.

Additionally, the BSS138 is RoHS compliant, meaning it adheres to environmental standards by being free from hazardous materials like lead, mercury, and cadmium.

Key Features:

• N-Channel MOSFET: As an N-Channel MOSFET, the BSS138 allows current to flow from drain to source when a positive voltage is applied to the gate, making it ideal for low-side switching applications in low-voltage circuits.
• Drain-Source Voltage (V_DS): With a 50V maximum drain-source voltage rating, the BSS138 is suitable for moderate voltage applications, ensuring reliable operation in low-power circuits and signal switching tasks.
• Continuous Drain Current (I_D): The BSS138 supports a continuous drain current of up to 350mA, making it suitable for low-power switching and signal amplification in space-constrained circuits.
• Low Gate Threshold Voltage (V_GS(th)): The gate threshold voltage is typically 1.3V, making it ideal for logic-level switching in 3.3V or 5V logic circuits, ensuring efficient operation without requiring a high voltage to turn on.
• Low On-Resistance (R_DS(on)): The BSS138 has a low on-resistance, which reduces conduction losses and improves switching efficiency, making it ideal for power-sensitive applications such as battery-operated devices.
• Compact SOT-23 Package: The SOT-23 package provides a small footprint, making the BSS138 ideal for surface-mount technology (SMT) and compact designs.
• RoHS Compliant: The BSS138 is RoHS compliant, meaning it is free from harmful substances like lead, cadmium, and mercury, ensuring it meets modern environmental standards.

Applications:

• Logic-Level Switching: The BSS138 is ideal for low-side switching in digital logic circuits where 3.3V or 5V logic is used. It is often used in microcontroller interfaces, I/O expansion, and switching applications requiring efficient control of low-voltage systems.
• Power Control Circuits: The BSS138 can be used in power management circuits, such as power gates, load switching, and voltage regulators, where it can efficiently control the flow of power to various sections of an electronic system.
• Battery-Powered Devices: Due to its low gate threshold voltage and low on-resistance, the BSS138 is an excellent choice for use in battery-powered circuits, including portable electronics, low-power sensors, and battery-operated gadgets, where power efficiency is essential.
• Signal Switching: The BSS138 is widely used in signal switching applications like audio signal routing, logic-level signals, and RF circuits, providing efficient and reliable low-power switching.
• Overcurrent Protection: The BSS138 is suitable for use in overcurrent protection circuits, where it can quickly disconnect a load if an overcurrent condition is detected, ensuring the safety of the circuit.
• Level Shifting: The BSS138 can be used in level-shifting applications, where it can interface different logic voltages (e.g., converting 5V logic to 3.3V logic), enabling interoperability between different systems.

With its low gate threshold voltage, compact SOT-23 package, and efficient switching characteristics, the BSS138 is the perfect choice for a wide variety of low-voltage switching and signal control applications in modern electronics.
