Pinout
The BZX84C18LT1G is a Zener diode. It typically comes in a SOT-23 package, which is a small surface-mount package with three pins. The functions of the pins are as follows:
1. Anode: This is the positive terminal of the Zener diode.
2. Cathode: This is the negative terminal and is marked with a band on the diode's body.
3. Not Connected (NC): The third pin is usually not connected in the typical configuration of a Zener diode in a SOT-23 package.
The primary function of the BZX84C18LT1G is to provide voltage regulation by maintaining a constant voltage (18V nominal) across its terminals when the reverse bias voltage exceeds the Zener breakdown voltage. This makes it useful for applications such as voltage reference, voltage stabilization, and protection circuits.
