PMBT3904,235 Typical application Circuitry

PMBT3904,235

The PMBT3904,235 is a small-signal NPN bipolar junction transistor (BJT) that is often employed for general purpose switching and amplification.

Principal Purpose: The PMBT3904,235 is intended for low-power switching and signal amplification applications.

Application Scenarios: It is widely used in diverse scenarios such as consumer electronics, signal processing circuits, and as a discrete component in digital logic circuits.

Parametric Characteristics: This transistor typically features a collector current (I_C) of up to 200 mA, a maximum collector-emitter voltage (V_CE) of 40 V, a maximum collector-base voltage (V_CB) of 60 V, and a maximum emitter-base voltage (V_EB) of 6 V. Its transition frequency (f_T) is also a considerable parameter, being above 100 MHz, which indicates suitability for RF applications.

Example Circuit – Common Emitter Amplifier:

Biasing the Transistor: Establish correct biasing for the PMBT3904,235 to operate in the active region.

Resistor for Collector Load: To adjust the required collector current, select the collector resistor R_C. Attach R_C to the positive supply V_CC and the collector (pin 1) of the PMBT3904,235.

Emitter Stabilization: Insert an emitter resistor R_E to stabilize the transistor's operation against temperature variations. Connect R_E between the emitter (pin 2) and the ground.

Input Signal Connection: Couple the input signal through a capacitor C_IN to the base (pin 3). This coupling capacitor blocks DC components to ensure only the AC signal is amplified.

Base Bias Resistors: Implement a voltage divider with resistors R1 and R2 to the base (pin 3) for proper biasing. The divider connects to V_CC and ground, with their junction providing a stable bias voltage to the base.

Output Coupling: Connect a capacitor C_OUT to the collector (pin 1) to the output load to block DC and pass only the amplified AC signal.

Design Considerations: The design must consider thermal management, ensuring the PMBT3904,235 does not exceed its maximum power dissipation. Proper biasing is crucial to avoid transistor saturation or cutoff, thus maintaining linearity. Moreover, the frequency response should be checked, especially for high-speed signals, to confirm that the amplifier's bandwidth matches the application requirements.

Incorporating the PMBT3904,235 into a circuit design involves meticulous attention to these details, ensuring the transistor functions as intended within the specific application's context. Addressing these considerations guarantees that the PMBT3904,235 will provide the expected performance, thereby achieving a successful and reliable circuit implementation.
