PMBT3904/8,215 Typical application Circuitry

The PMBT3904/8,215 denotes a product series number that typically refers to a variant of the PMBT3904, which is an NPN general-purpose transistor. This type of transistor is widely used in electronic circuits for switching and amplifying signals.

Key Parameters:

The PMBT3904/8,215 is characterized by a maximum collector current (Ic) of 200 mA, a maximum collector-emitter voltage (Vceo) of 40 V, and a maximum power dissipation (Ptot) of around 500 mW. It also has a DC current gain (hFE) that can range widely but is often specified for a certain minimum at a given collector current in its datasheet.

Typical Application:

A classic application of the PMBT3904/8,215 is in a basic audio amplification circuit.

Circuit Integration:

In an audio amplifier circuit using the PMBT3904/8,215, the transistor can be configured as a common-emitter amplifier:

1. Biasing the Transistor: The base (pin 1) of the PMBT3904/8,215 requires biasing with a voltage divider network composed of two resistors R1 and R2 connected from Vcc to the ground, with the base connected at the node between R1 and R2.

2. Input Coupling: An input capacitor (Cin) is connected between the audio input source and the base of the PMBT3904/8,215 to couple the audio signal without affecting the DC bias.

3. Emitting Stability: A resistor (Re) is connected between the emitter (pin 2) and ground to stabilize the operating point against temperature variations and to set the gain of the amplifier.

4. Collector Load: The collector (pin 3) connects to the positive supply voltage (Vcc) through a load resistor (Rc), which determines the output voltage swing and power dissipation.

5. Output Coupling: An output capacitor (Cout) couples the amplified audio signal from the collector to an output device, such as a speaker, and blocks DC.

Design Considerations:

It's crucial to consider biasing properly to operate the PMBT3904/8,215 within its active region for linear amplification. Heat sinking may be necessary for higher power applications. The signal frequency response is affected by the choice of capacitors and resistors, which must be selected based on desired audio characteristics. It's also essential to ensure that the transistor operates within its maximum ratings to prevent damage.
