PMBT3904M,315 Typical application Circuitry

PMBT3904M,315

The PMBT3904M,315 is a variant of the widely used PMBT3904 transistor, which is a general-purpose NPN bipolar junction transistor (BJT) used for amplification and switching purposes.

Function of the Chip: The PMBT3904M,315 functions as a switch or amplifier within a circuit. It controls current flow between the collector and emitter, based on the current at the base terminal.

Application Scenarios: Common applications include driving small loads, digital logic switches, signal amplification, and as a switch for LEDs, motors, and other small electronic components.

Parameter Characteristics: The PMBT3904M,315, similar to the standard PMBT3904, typically features a maximum collector current (Ic) of about 200 mA, a maximum collector-emitter voltage (Vce) of 40V, and a collector-base voltage (Vcb) of 60V. It also has a maximum power dissipation around 625 mW, with varying gain (hFE) depending on the exact specifications of the variant.

Example Circuit Connection: An example circuit using the PMBT3904M,315 could be a simple LED driver.

Power Supply Requirements: Begin by determining the supply voltage $ V_{CC} $ required for the circuit, ensuring it is sufficient to drive the LED and the PMBT3904M,315.

Calculating the Current-Limiting Resistor: Calculate the value of the current-limiting resistor $ R_L $ to protect the LED. Use $ R_L = \frac{V_{CC} - V_{LED}}{I_{LED}} $, where $ V_{LED} $ is the forward voltage of the LED and $ I_{LED} $ is the desired current through the LED.

Connecting the LED: Connect the anode of the LED to $ V_{CC} $ and its cathode to one end of $ R_L $, with the other end of $ R_L $ going to the collector (C, pin 3) of the PMBT3904M,315.

Grounding the Emitter: Attach the emitter (E, pin 2) of the PMBT3904M,315 to the ground of the circuit.

Adding a Base Resistor: Add a base resistor $ R_B $ to the base (B, pin 1) of the PMBT3904M,315 to control the base current. $ R_B $ can be determined using $ R_B = \frac{V_{CC} - V_{BE}}{I_B} $, with $ V_{BE} $ typically around 0.7V for silicon BJTs and $ I_B $ calculated to ensure the transistor is in saturation when the LED is supposed to be on.

Input Signal: Apply the input signal to the base resistor $ R_B $. When the input signal is high, the transistor should saturate and allow current to flow from the collector to the emitter, thus lighting the LED.

Design Considerations: The design of the circuit with PMBT3904M,315 needs to account for the current gain (hFE) of the transistor to ensure proper saturation. Additionally, the power dissipation within the PMBT3904M,315 should be checked, especially if the transistor is expected to switch frequently or drive higher currents.

In conclusion, when using the PMBT3904M,315 in a circuit, careful attention must be given to the calculation of resistors and the power dissipation. Proper use of the PMBT3904M,315 in accordance with its specifications will ensure a reliable and efficient design.
