The BD135 transistor works well in various settings, whether you are working on commercial projects, educational circuits, or hobby electronics. You can use it as a switch or driver to control loads of up to 1.5A. This versatility makes it a helpful component in many types of circuits.
You might use the BD135 in an audio amplifier circuit, where it can boost the sound signal. It is also suitable for other stages in electronic circuits where signal amplification is needed. By understanding the transistor’s capabilities, you can easily find places in your designs where the BD135 fits perfectly, whether for switching or amplifying tasks.
To get the most out of the BD135 transistor in the long run, you should avoid pushing it beyond its limits. Do not use it to drive loads that exceed 1.5A or require more than 45V. If you are working with loads that draw more than 200mA, it’s a good idea to use a heatsink to keep the transistor from overheating.
In addition, always make sure you use a proper base resistor with the transistor. The operating temperature should stay between -55°C and +150°C to ensure stable and reliable performance. Following these simple guidelines will help maintain the efficiency and lifespan of your BD135 transistor in any circuit.
The BD135 comes in a TO-126 package, which is compact and easy to work with. This package helps manage heat and allows you to easily integrate the transistor into your projects.
This transistor is an NPN type, which means it allows current to flow from the collector to the emitter when a positive voltage is applied to the base. NPN transistors are commonly used in various switching and amplification circuits.
The BD135 can handle a maximum collector current of 1.5A, allowing it to control larger loads without any issues. This makes it suitable for driving components like LEDs, motors, and relays.
The transistor can withstand a maximum voltage of 45V between its collector and emitter. This voltage rating ensures the BD135 can be used in circuits where higher voltage switching is required.
Just like the collector-emitter voltage, the maximum collector-base voltage is also 45V. This gives the BD135 the flexibility to work in circuits where it must handle a range of voltage levels.
The maximum voltage allowed between the emitter and the base is 5V, so you’ll need to make sure that the base-emitter voltage stays within this range for proper operation.
The transistor can dissipate up to 12.5W of power, which means it can handle heat well and maintain stable performance in your circuit, as long as proper cooling measures, like a heatsink, are used.
With a transition frequency of 190 MHz, the BD135 is fast enough for many high-speed switching applications. This feature makes it a good choice for circuits requiring quick responses.
The BD135 provides a wide range of DC current gain, between 40 and 250, depending on the version you choose. This flexibility allows you to select the gain value that best suits your application needs.
The BD135 can operate in a wide temperature range, from -55°C to +150°C. This makes it reliable in various environments, from cold to hot, ensuring stable performance in many applications.
You can use the BD135 in circuits that require audio amplification or other signal boosting tasks. It strengthens the signal, making it louder or clearer in audio applications, or enhancing the quality of other electronic signals.
This transistor is excellent for switching and controlling loads of up to 1.5A, such as LEDs, motors, and relays. Its ability to handle these loads makes it versatile in many electronic projects.
The BD135 can also be used in motor driver circuits, providing control over motors in various devices. This application is especially useful when you need to drive small motors in robotic or mechanical projects.
You can integrate the BD135 into battery charger circuits, where it helps regulate the charging process. This is useful in devices that require controlled and safe charging of batteries.
The transistor can be part of power supply circuits, where it helps manage and regulate power distribution to different components in the circuit.
The BD135 is often used in Darlington pairs, a configuration that boosts current gain. This allows you to use it in applications that need higher current output without sacrificing efficiency.
