MPS6513

The MPS6513 is classified as a single bipolar junction transistor (BJT) used in various applications and with a range of different working principles. The device is particularly well suited to low to medium power applications in which switch mode, linear and power amplification is required. Its construction is such that it makes possible a wide range of configurations, including a full differential transistor pair and complementary push-pull circuit. This makes it ideal for applications where a high degree of efficiency and gain is required.

The MPS6513 is a low to medium powered BJT with a maximum collector current of up to 250mA and a maximum collector voltage of up to 125V. It is usually packaged in a TO-3-mounted package with a 2.5mm lead length. The transistor has three terminals: emitter, collector and base. In a common emitter configuration, current flows from the emitter to the collector when the base is forward biased. Conversely, when the base is reverse biased, the current flow is blocked.

The MPS6513 is most commonly used in switch mode power supplies, where the switching action requires precise control over the collector current and voltage. In this case, the transistor is operated as an amplifier, with the switching action established by the conduction angle of the base-collector junction. This duty cycle determines the amount of power that is supplied to the load, with the duty cycle controlled by the power supply itself.

Another popular use of the MPS6513 is in audio amplifiers and other circuits requiring high power audio amplification. Here, the amplifier is operated in either class A or B mode, where the transistors are used as push-pull switches. This allows for higher power gain and greater efficiency, particularly in class B amplifiers.

The MPS6513 is also used in linear power amplifiers, where the device is used as an amplifier and the output signal is adjusted by varying the current or voltage across the base-collector junction. In this case, the conduction angle is adjusted to optimize the gain and power efficiency.

In conclusion, the MPS6513 is an extremely versatile, low to medium power BJT. It is ideal for applications where switch mode, linear and power amplification are all required, as it can be configured in a range of different configurations including a full differential transistor pair and complementary push-pull circuit. Its maximum collector current of up to 250mA and maximum collector voltage of up to 125V make it suitable for a wide range of applications, making it one of the most popular BJTs available.
