Physical Characteristics:
- Package Type: The BC807-40 typically comes in a TO-92 package, which is a cylindrical plastic housing with three leads extending from the base. This package is compact and suitable for through-hole mounting on printed circuit boards (PCBs).
- Dimensions: The TO-92 package generally has a height of about 4.5 mm and a diameter of approximately 3.5 mm, making it easy to integrate into various designs.
Electrical Specifications:
- Type: PNP Transistor
- Maximum Collector-Emitter Voltage (Vce): The BC807-40 can handle a maximum Vce of 45 volts, making it suitable for low to moderate voltage applications.
- Maximum Collector Current (Ic): It has a maximum collector current rating of 800 mA, allowing it to drive moderate loads.
- DC Current Gain (hFE): The transistor exhibits a current gain (hFE) ranging from 100 to 600, depending on the specific operating conditions. This high gain makes it effective for amplification purposes.
- Transition Frequency (fT): The BC807-40 has a transition frequency of around 150 MHz, indicating its capability for high-frequency applications.
Thermal Characteristics:
- Junction Temperature (Tj): The maximum junction temperature is typically rated at 150°C, which allows for operation in a variety of thermal environments.
- Thermal Resistance: The thermal resistance from junction to ambient is relatively low, ensuring efficient heat dissipation during operation.
Applications:
The BC807-40 is widely used in:
- Signal Amplification: It is suitable for audio and radio frequency amplification.
- Switching Applications: The transistor can be used in various switching circuits, including relay drivers and motor control.
- General Purpose Circuits: Its versatility makes it a common choice in consumer electronics, automotive applications, and industrial control systems.
Pin Configuration:
- Pin 1 (Emitter): The emitter is connected to the load or the circuit that requires current.
- Pin 2 (Base): The base is used to control the transistor's operation, allowing for modulation of the current flowing from collector to emitter.
- Pin 3 (Collector): The collector is connected to the power supply or the load that the transistor is driving.
Conclusion:
The BC807-40 from Changjiang Electronics is a reliable and versatile PNP transistor suitable for a wide range of electronic applications. Its combination of moderate voltage and current ratings, along with a high gain, makes it an excellent choice for both hobbyists and professional engineers looking to implement amplification or switching functions in their designs.
