The base of the transistor is biased using a 10 K Ohm resistor(R3) in parallel to the 1 K Ohm resistor(R2) plus base-emitter junction resistance(in series). OR R3 ( R2+RBE ). Proper biasing of the base ensures adequate base current to turn ON the transistor.

When the switch is closed, the base of the transistor is biased, and current flows to the base of the transistor. Due to this biasing current, 2N3904 goes to the saturation state and the LED turns ON.

2N3904, BC547, BC550, BC549 & BC548 (These are the nearest possible replacement or equivalent of 2SC828 transistor. The pin configuration of these transistors may different from C828, therefore check pinout of any transistor you are willing to replace with C828.

To get stable performance from this transistor for long period do not drive load more than 100mA and 25V DC. Always use a suitable base resistor and do not store and use the transistor in temperature below -55 Celsius and above 150 Celsius. 2ff7e9595c
