2SA07940R

2SA07940R is a bipolar junction transistor (BJT) classified as a single transistor, designed for analog and digital circuits, with a variety of potential uses in telecommunication and automotive applications, or any application that requires a high reliability level. This type of transistor is integrated into discrete components and is available in a plastic case with an epoxy molding.

The BJT has three terminals, the emitter, the base, and the collector. This transistor functions by using an injection of minority carriers (electrons or holes) into the collector current by the emitter. The emitter-base junction is forward biased and the collector-base junction is reverse biased. The minority carriers coming from the emitter pass through the base and are collected in the collector. In other words, the current received by the collector is the result of the current conducted from the emitter. This is known as the “Principle of E-B-C”.

The 2SA07940R is a fast switching high-speed and low-power transistor. It uses advanced bipolar technology to achieve high frequency operation with excellent temperature and input current characteristics. It has a low noise figure and high-speed operation up to 250MHz, making it suitable for RF applications. This transistor has a maximum collector current of 250 mA, with a voltage drop of 2 V. It also offers a high degree of stability and low distortion noise.

In addition to its fast switching capability, the 2SA07940R is also extremely reliable, which is important for many of the applications it is intended for, such as automotive electronics and telecommunication systems. It is rated using the AEC-Q107 standard, which is a strict international automotive requirement that requires products to meet high quality standards and maintain consistent performance over time. This transistor is also tested to ensure reliability up to temperatures of 125°C, making it well suited for high temperature and vibration environments.

The 2SA07940R is a bipolar junction transistor specifically designed for fast switching applications with high reliability. It provides quick switching high-speed operation, low-power, low noise figure, and high voltage drop. This makes it ideal for use in applications such as digital circuits, telecommunication systems, and automotive electronics. It also meets the AEC-Q107 standard for automotive electronic components and offers high temperature tolerance, making it the ideal choice for harsh environments.
