The BZX84C12-HE3-18 is a single Zener diode commonly used in various applications ranging from the automotive industry, consumer products, and industrial applications. This diode is specifically designed to protect sensitive electronics from power surges, stabilise voltage signals, and prevent reverse voltage from entering circuits. The BZX84C12-HE3-18 is a medium power Zener diode with a Zener voltage of 12 V and a maximum power rating of 0.25 W. It is housed in the SOD-80 package, which offers excellent thermal and electrical features and a compact form factor.

The BZX84C12-HE3-18 works on the principle of avalanche breakdown. The diode consists of an N-type semiconductor layer sandwiched between two P-type layers. The N-type layer forms the junction between the P-type layers, and this junction is known as the Zener Region. This junction is the primary active part of the diode and is responsible for its operation. When a certain reverse voltage is applied to the Zener region, the covalent bonds between the atoms of the N-type semiconductor layer weaken and ionisation occurs, allowing electrons to cross the junction. This process is called Avalanche Breakdown, which is responsible for the diode’s action as a voltage regulator.

The BZX84C12-HE3-18 is important in applications where a stable power supply or a constant voltage reference is necessary. When used as a voltage regulator, the diode can provide a constant voltage output regardless of changes in load current or input voltage. This makes the diode ideal for applications such as voltage monitoring or protection circuits, automotive lighting and instrumentation, power supply design, and voltage reference circuits. In addition, the diode can also be used to protect sensitive electronic components from reverse voltage, transients, and overvoltage.

The BZX84C12-HE3-18 is an efficient and cost effective solution for circuit protection and voltage regulation applications. It is available at various online retailers and comes in a variety of packages. The diode is RoHS compliant and offers excellent thermal and electrical protection against overvoltage and transients, making it a reliable choice for various industrial and consumer applications.
