The BZX84C4V3 is a 500mW, 3.6-volt Zener diode with a maximum allowed power dissipation of 500mW. It belongs to the single diode type and is specially designed for use in a wide variety of applications.

The BZX84C4V3 diode is a unidirectional device having a cathode marked with a black band. It has an impedance range of 24.5k ohms @ 1mA, scalable to 22.5k ohms @ 10mA. The package includes a gold-plated Nickel connector and a molded plastic package with two pins.

The BZX84C4V3 is designed to protect equipment from over-voltage or shorts when used in combination with other components. It is a cost-effective solution for a variety of applications, especially those requiring a low cost and well-engineered hybrid device. It is ideally suited for use in cell phone/PDA protection, laptop/PC regulation, automotive backlighting, and a variety of other applications.

The BZX84C4V3 Zener diode works on the principle of tunneling. Its integrated junction is the heart of the device. It allows current to flow in only one direction, from anode to cathode, when a forward voltage is applied. As the voltage increases, the diode starts to conduct, and a voltage is dropped across the diode. When the applied voltage reaches a certain level, the Zener voltage, the diode breaks down, and the voltage across it dives sharply.

The breakdown voltage of the BZX84C4V3 diode is 3.6V. Its direct reverse current rating is typically 27.4mA, and its total power dissipation is 500mW. This diode can function over a wide temperature range, from -40°C to +150°C.

The main applications of the BZX84C4V3 Zener diode are in over-voltage protection, voltage regulation and voltage clamping. It can also be used to provide a stable reference voltage to maintain the operating voltage of a device, to limit a signal\'s magnitude or to block a signal of a certain frequency. The diode can also be used in logic and regulated power systems, television circuits and current regulation in battery-operated equipment.

The BZX84C4V3 single diode is an easy-to-use, low-cost, durable and reliable semiconductor device, ideal for many applications. It is highly suited to high frequency, high temperature and high voltage environments, making it an ideal choice for a range of applications.
