The C828 transistor is a commonly used NPN bipolar junction transistor (BJT). It is a low-power, general-purpose transistor that is widely used in electronic circuits. The C828 transistor is a small-signal transistor, which means that it is designed to amplify low-level signals.
Pinout of C828 Transistor
The C828 transistor has three pins and comes in a TO-92 package. The pinout of the C828 transistor is as follows:
- The first pin is the collector (C) and is typically marked with a black color band or dot. The collector is the output terminal of the transistor and is connected to the load in a circuit.
- The second pin is the base (B) and is typically marked with a red color band or dot. The base is the input terminal of the transistor and is used to control the flow of current between the collector and emitter.
- The third pin is the emitter (E) and is typically marked with a green color band or dot. The emitter is the common terminal of the transistor and is connected to the ground or negative supply in a circuit.

Alternate of C828 Transistor
There are several transistors that can be used as an alternative to the C828 transistor. These transistors are typically low-power, general-purpose transistors that have similar characteristics and can be used in a wide range of electronic circuits. Some of the alternatives to the C828 transistor are:
- 2N3904: This is an NPN transistor with a maximum voltage rating of 40V and a maximum current rating of 200mA. It has a DC current gain range of 100 – 300 and is commonly used in low-power amplifiers, switching circuits, and oscillator circuits.
- BC547: This is also an NPN transistor with a maximum voltage rating of 45V and a maximum current rating of 100mA. It has a DC current gain range of 110 – 800 and is commonly used in low-power amplifiers, switching circuits, and voltage regulators.
- 2SC1815: This is another NPN transistor with a maximum voltage rating of 50V and a maximum current rating of 150mA. It has a DC current gain range of 70 – 700 and is commonly used in low-power amplifiers, switching circuits, and oscillator circuits.
It is important to note that while these transistors can be used as alternatives to the C828 transistor, they may not have identical characteristics and performance. Therefore, it is always recommended to consult the datasheet provided by the manufacturer to ensure that the alternative transistor is suitable for the specific application.
Complement of C828 Transistor
The complement of the C828 transistor would be a PNP transistor with similar characteristics and specifications. One example of a complementary PNP transistor to the C828 is the A1015 transistor. The A1015 is a small signal PNP transistor with a maximum voltage rating of 50V, a maximum current rating of 150mA, and a DC current gain range of 70 – 700. It is commonly used in low-power amplifiers, switching, and oscillator circuits. However, it is important to note that while the A1015 can be used as a complementary transistor to the C828, it may not have identical characteristics and performance, so it is always recommended to consult the datasheet provided by the manufacturer to ensure that the complementary transistor is suitable for the specific application.
