NZQA6V8AXV5T2

TVS (transient voltage suppressors) diodes are widely used for their capability to prevent malfunction of equipment while handling high-voltage, high-current, or electrostatic discharge (ESD) spikes. The NZQA6V8AXV5T2 is a transient voltage suppressor diode device that has been designed by NXP Semiconductors to protect various pieces of equipment such as automotive systems, computer peripherals, and laptops from voltage transients.

The NZQA6V8AXV5T2 is an Unidirectional device with a high-energy standoff voltage of 6V and an avalanche voltage of 8V. It comes in a compact, SOD-123 package with a low on-resistance of 0.5V typical and an eighth-brick flat no-lead design that provides excellent thermal characteristics. The device has an operational current range of 2 to 150 mA.

Working Principle: The primary function of the NZQA6V8AXV5T2 is to protect various pieces of equipment from voltage transients caused by ESDs, and other surges generated by inductive switching. When a voltage in excess of the device\'s robust energy rating is applied, the TVS diode becomes active and begins to conduct current to discharge the voltage. This occurs via a phenomenon called “avalanche breakdown” which is when the width of a reverse-biased PN junction is increased exponentially due to an increase in the electric field voltage. As the electric field increases beyond a certain threshold, a large number of electron-hole pairs are generated, resulting in a high current.

These TVS diodes can also be used in power supply applications. In this case, the NZQA6V8AXV5T2 functions as a Zener diode that can regulate the output voltage, by releasing current once the input voltage exceeds a certain threshold. This provides a simple and reliable way to protect sensitive circuits from overvoltage and transients.

The NZQA6V8AXV5T2 is an effective TVS diode that is perfect for protecting a variety of automotive systems, computer peripherals, and other pieces of high-end equipment from voltage transients and ESDs. This device’s low on-resistance ensures low power consumption while maintaining excellent thermal performance. Its eighth-brick flat no-lead design further improves its efficiency by providing better thermal characteristics.
