<div class=\'entry-content\'> <p>AOZ8819DI-05 is a device that integrates a strong transient voltage suppression diode and an Electro-Static Discharge (ESD) protection circuit. It is primarily used to protect electronic devices from electrical transients or Electro-Magnetic Interference (EMI). AOZ8819DI-05 is a surface mounted, single-pole, transient voltage suppression diode. It is designed to provide maximum protection in a variety of applications, such as power supplies, battery packs, automotive electronics, telecom and datacom equipment, and any other type of equipment that requires strong ESD protection.</p> <h2>Application Field</h2> <p>AOZ8819DI-05 is suitable for many applications, including automotive electronics, computers, wireless communications, renewable energy applications, and commercial and home appliances. AOZ8819DI-05 can be used in high temperature, harsh environment applications due to its excellent heat dissipation and thermal insulation features. It is also suitable for LCD display applications because of its low leakage current, low clamping voltage, and high surge performance.</p> <h2>Working Principle</h2> <p>AOZ8819DI-05 works by clamping transient overvoltage to a safe, predetermined voltage level. This happens in three stages: 1. The diode reverse-biases in a transient surge, reducing the exceed voltage below the predetermined limit. 2. The diode clamps the surge voltage at a preset level. 3. The diode then slowly discharges to the safe voltage level.</p> <p>When the overvoltage is greater than the reverse breakdown voltage, the diode begins to conduct current, slowly reducing the overvoltage until the voltage across the diode reaches its predetermined clamping voltage. This clamping voltage is designed to be low enough to not cause any damage to the device connected to the diode.</p> <p>When the surge has dissipated, the diode will slowly discharge the voltage until it reaches its safe voltage level. AOZ8819DI-05 devices are designed to have a low self- discharge rate, meaning they can remain in the discharged state for an extended period of time.</p> <p>AOZ8819DI-05 has a low capacitance and is designed to stay within the low capacitance rating even after thousands of surge events. This makes it an ideal choice for applications that require a low capacitance. Furthermore, AOZ8819DI-05 is also designed for reliable operation in high temperature and harsh environment applications.</p></div>
