The BSS138 is a popular N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by various companies, including ZRE (Zhongrong Electronic). It is widely used in electronic circuits for switching and amplification applications due to its efficient performance and compact size.
Key Features and Specifications:
-
Package Type: The BSS138 typically comes in a small SMD (Surface Mount Device) package, such as the SOT-23, which allows for easy integration into compact circuit designs. The SOT-23 package has three leads, making it suitable for automated assembly processes.
-
Electrical Characteristics:
- Drain-Source Voltage (V_DS): The maximum voltage that can be applied between the drain and source terminals is around 50V, making it suitable for low to moderate voltage applications.
- Gate-Source Voltage (V_GS): The maximum gate-source voltage is typically ±20V, allowing for a wide range of control voltages.
- Continuous Drain Current (I_D): The BSS138 can handle a continuous drain current of approximately 220mA at room temperature, which can vary with temperature and thermal management.
- R_DS(on): The on-resistance (R_DS(on)) is low, typically around 3.5 ohms at a gate-source voltage of 10V, which minimizes power loss during operation.
-
Threshold Voltage (V_GS(th)): The threshold voltage, which is the minimum gate-source voltage required to turn the MOSFET on, is usually between 1.0V and 3.0V. This characteristic makes the BSS138 suitable for low-voltage applications.
-
Switching Speed: The BSS138 has fast switching capabilities, making it ideal for high-speed applications. Its rise and fall times are typically in the nanosecond range, allowing for efficient operation in digital circuits.
-
Applications: The BSS138 is commonly used in various applications, including:
- Level shifting in digital circuits.
- Switching power supplies.
- Motor control circuits.
- Signal amplification.
- LED drivers.
-
Thermal Characteristics: The BSS138 has a thermal resistance that allows it to operate effectively within specified temperature ranges. Proper heat dissipation techniques should be employed in high-current applications to prevent thermal overload.
Physical Characteristics:
- Lead Configuration: The BSS138 has three leads: Gate (G), Drain (D), and Source (S). The arrangement of these leads is crucial for correct circuit implementation.
- Marking: The device is often marked with a specific code to identify the manufacturer and part number, which is essential for sourcing and replacement.
Conclusion:
The BSS138 from ZRE is a versatile and efficient N-channel MOSFET that is well-suited for a variety of electronic applications. Its compact size, low on-resistance, and fast switching capabilities make it a preferred choice for engineers and hobbyists alike in designing modern electronic circuits.
Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
