This article explains the C828 transistor pinout, equivalent, datasheet, alternate, and uses. Transistor C828 is the most common general-purpose NPN transistor and is a BJT transistor. C828 can be used as an amplifier and for switching purposes in electronic circuits. It can handle a load of up to 100 mA, which is quite a fair amount of current when driving other components in electronic projects. As an amplifier, it can drive 400 mW, and the max DC current gain value is 520. Transistor C828 is available in different DC gain values; these values can be identified by looking at the last alphabet after the transistor number. If the last alphabet is “Q,” the gain will be 130 to 260; if “R,” the gain will be 180 to 360; and if “S,” then the gain will be 260 to 520. Therefore, you can choose as needed for the requirements of your circuit.
C828 Transistor pinout
The C828 is manufactured in a plastic TO-92 case. It consists of 3 terminals, or leads; these leads are called the emitter, collector, and base leads.
