C1815 General Purpose NPN Transistor - Overview

The C1815 is a general-purpose NPN transistor commonly used in small signal applications. With a maximum voltage rating of 50V and a maximum current rating of 0.15A, it is well-suited for low-power switching and amplification tasks. It's often used in circuits involving LEDs, signal amplification, and general switching applications.

Wiring Instructions

The C1815 NPN transistor can be used in various circuits. Here's how to wire it in a simple switching circuit:

Collector (Pin 3): Connect to the load (e.g., an LED or motor) and then to the positive supply voltage (Vcc).
Base (Pin 1): Connect to a current-limiting resistor and then to the control signal (e.g., from an Arduino or microcontroller).
Emitter (Pin 2): Connect to ground (GND).

Sample Code

Here’s an example of how to control the C1815 transistor with an Arduino. The transistor will switch an LED on and off based on the digital output from the Arduino:

int transistorPin = 3;  // Pin connected to the base of the C1815

void setup() {
  pinMode(transistorPin, OUTPUT);  // Set the transistor pin as an output
}

void loop() {
  digitalWrite(transistorPin, HIGH);  // Turn the transistor ON (LED ON)
  delay(1000);  // Wait for 1 second
  digitalWrite(transistorPin, LOW);   // Turn the transistor OFF (LED OFF)
  delay(1000);  // Wait for 1 second
}
