BD13910STU: A Single Bipolar Transistor for an Array of Applications

The BD13910STU is an advanced ranging transistor suitable for an array of applications, such as audio amplifier boosters, to computer-related components and wireless communication products. This single bipolar junction transistor (BJT) is a dependable and relatively inexpensive component, capable of consuming minimal amounts of power while still providing excellent results. Let’s examine a few attributes coated in this device.

Features and Applications

The BD13910STU is offered in a lead (Pb) free, plastic surface-packaged device with four leads arranged as an Easy 125 package. It comes with a 1.5KΩ Built-in Collector-emitter resistor, allowing it to be used in both common emitter and common base applications without the need of an external resistor. It also provides performance enhancements such as high speed with a breakneck hFE of >700 at 1.0A, 350mA with a forward current of 1 mA and >500 for a static current of 100 mA.

The BD13910STU’s features present a range of applications too. It can efficiently work as an audio pre-amp booster, providing support for higher volume output. Due to its high-speed performance and power-efficiency for low-speed applications, it can be used in computer-related components such as CPUs and chipsets. In the field of wireless communication, it can be used as an RF amplifier to reduce the noise coming from mobile devices. Additionally, this transistor is suitable for various audio applications such as audio mixers and power amplifiers.

Working Principle

The BD13910STU is a single bipolar transistor, which means it’s made up of three elements: collector, base and emitter. When electric current flows through the transmitter in the forward direction, it is called forward bias. As current flows, it causes electrons to be injected into the base, creating an amplified electric current in the collector. It’s quite similar to how a pipe can transport water from one place to another — the electric current acts like the water, “flowing” through the transistor.

Another factor to consider is the gain of the transistor. Gain is the ratio of the output signal compared to the input signal. This is usually measured in decibels (dB) or decibels relative to one milliwatt (dBm). For the BD13910STU, the gain measurements equate to 14dB at 1kHz and 16dB at 10kHz.

Maintenance Tips for the BD13910STU

Using the BD13910STU is quite simple when it comes to installation. Due to its well-structured design, it’s safe from overloads, open-circuits and short-circuits. However, proper maintenance is still required to ensure the device is working optimally.

Periodic maintenance is recommended to test the device, inspect for dust, make sure all the pins are correctly fitted and ensure the characteristic data has not changed over time. Additionally, the power source must be completely turned off when inspecting the device. Finally, always refer to the documents provided by the manufacturer when it comes to operation and maintenance.

Conclusion

The BD13910STU is an advanced ranging single bipolar transistor with an array of applications. Its performance-enhancing features and low power consumption help keep both cost and size down. Its easy-to-install design and maintenance tips make it an ideal choice for various audio, wireless communication and computer-related components.
