BSS84

The BSS84 is a type of N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by Changjiang Electronics. It is designed for low-voltage applications and is commonly used in switching and amplification circuits.

Key Features:

1. Package Type: The BSS84 typically comes in a compact SOT-23 package, which is a surface-mount device (SMD) that allows for efficient use of PCB space. The small footprint makes it suitable for applications where space is at a premium.

2. Electrical Characteristics:

   • Drain-Source Voltage (V_DS): The BSS84 can handle a maximum drain-source voltage of around 30V, making it suitable for low-voltage applications.
   • Continuous Drain Current (I_D): It can support a continuous drain current of approximately 0.5A, which is adequate for many low-power switching applications.
   • Gate Threshold Voltage (V_GS(th)): The gate threshold voltage typically ranges from 1V to 3V, allowing it to be driven by low-voltage logic levels.

3. Performance:

   • R_DS(on): The on-resistance (R_DS(on)) is low, typically around 0.5 ohms at a gate-source voltage of 10V, which minimizes power loss during operation.
   • Switching Speed: The BSS84 features fast switching capabilities, making it suitable for high-frequency applications.

4. Thermal Characteristics: The device has a reasonable thermal resistance, allowing it to operate efficiently without overheating under normal conditions.

5. Applications: The BSS84 is widely used in various applications, including:

   • Low-side switching in power management circuits.
   • Signal switching in audio and RF applications.
   • Level shifting and interfacing between different voltage domains.

6. Pin Configuration: The SOT-23 package typically has three pins:

   • Gate (G): The control terminal that regulates the flow of current between the drain and source.
   • Drain (D): The terminal through which the current flows out of the MOSFET.
   • Source (S): The terminal through which the current enters the MOSFET.

Summary:

The BSS84 from Changjiang Electronics is a versatile and efficient N-channel MOSFET suitable for a variety of low-voltage applications. Its compact size, low on-resistance, and fast switching capabilities make it an excellent choice for designers looking to optimize space and performance in electronic circuits.
