1N4148 Pinout Diagram
The 1N4148 is a standard fast-switching diode widely used in electronics for low current, high-speed switching applications. It has two primary terminals: the Anode and the Cathode. Below is a description of the pinout configuration of the 1N4148 diode.
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | Anode (+) | The positive terminal of the diode. Current enters through this pin during forward bias. |
| 2 | Cathode (-) | The negative terminal of the diode. Current flows out of this pin during forward bias. |
Understanding the pinout configuration is essential for correctly using the 1N4148 diode in electronic circuits. The Anode is the positive terminal, while the Cathode is the negative terminal, dictating the direction of current flow during forward bias operation.
