BC 807-25 E6433

The BC 807-25 E6433 is a NPN bipolar planar epitaxial silicon transistor manufactured by Philips Semiconductor. This transistor is commonly used in various applications, including audio amplifiers, radio-frequency amplifiers, switching circuits, and voltage regulation.

The BC 807-25 E6433 is a Planar epitaxial silicon NPN transistor with a relatively low collector-emitter breakdown voltage of 5 volts. It has a current gain of up to 500 and its power dissipation is up to 500 milliwatts. It also has an operating junction temperature range of up to 150 degrees Celsius. The transistor is also suitable for use in high-frequency applications due to its high-frequency capability of up to 500 MHz.

The BC 807-25 E6433 transistor has a standard lead form with a curved collector, so it can be easily soldered onto a circuit board. The transistor has four pins, with the emitter and collector pins having the same polarity. The base pin is connected to the emitter, and the collector and base pins are connected to the collector. The gate pin also has to be connected to the collector for proper functioning.

The working principle of this transistor is based on the principle of a bipolar junction transistor (BJT). It consists of two p-n junctions in opposite directions. When a voltage is applied to the base terminal, current flows through the base-emitter junction and the base-collector junction. This causes a current amplification in the collector-emitter junction. This amplified current is used for applications such as amplifying sound signals or controlling the speed or voltage of electric motors.

The most common application of the BC 807-25 E6433 is in audio amplifiers. This transistor is used in a wide variety of audio amplifiers, due to its low distortion and high power output. This transistor can also be used in radio-frequency amplifiers and switching circuits. In these circuits, it is used to amplify the input signal and switch the circuit on and off. It can also be used in voltage regulation applications, where it acts as a switching component to control the output voltage.

The BC 807-25 E6433 is a versatile transistor with a range of applications. It can be used in both low power and high power applications, making it a popular choice for general purpose applications. It is also relatively easy to solder and is capable of operating at high frequencies. This makes it an ideal choice for radio-frequency or high-frequency amplification applications.
