The V5.5MLA0805LNH is an overvoltage surge protection device from Vishay, a major supplier of discrete semiconductor components. The device is a Multi-Line Array (MLA) of TVS (Transient Voltage Surge) diodes designed to protect various types of electronic equipment from overvoltage spikes. This device is part of the Vishay\'s family of TVS-Varistors, MOVs (Metal Oxide Varistor) devices that can effectively absorb a wide range of overvoltage events without false triggering or damage to the protected equipment.

The V5.5MLA0805LNH can provide protection from voltage levels up to 5.5 V, making it well suited for the protection of low-voltage electronic components such as MEMs, displays, interfaces, data lines and other sensitive parts. The device is in the form of an array of four diodes connected in series, which forms a protection circuit with two legs. This ensures that an external overvoltage event induces a current in the opposite direction of the input voltage, causing the device to absorb the overvoltage and protect the electronic component. The device also contains a low leakage current path that allows very low current to flow when not exposed to a surge event.

The V5.5MLA0805LNH is designed to meet the requirements of AEC-Q101, a stringent automotive qualification standard. This is important for the protection of automotive electronic components, as they are often exposed to severe operating conditions. The device is also suitable for other applications such as consumer and industrial applications where safety and reliability are important.

The V5.5MLA0805LNH is in a small form factor, making it ideal for space constrained applications. The device is available in a standard 805 package, with a footprint of just 0.8 x 0.5 mm. This allows it to be used in a wide range of applications, from board-level designs to power modules.

The operating temperature range of the V5.5MLA0805LNH is from -55°C to +85°C, making it suitable for a wide range of applications. The device also includes a low-profile, ruggedized leadless design with an industry-standard SMD solder joint. This ensures a reliable connection and fast installation, even in the most demanding environments. The device also has ESD immunity of up to ±12 kV Human Body Mode for improved reliability and tolerance to electrostatic discharge.

In summary, the V5.5MLA0805LNH is an overvoltage surge protection device designed for protection of low-voltage electronic components in automotive, consumer and industrial applications. The device is in the form of an array of four diodes connected in series, providing effective protection from overvoltage events. The device is available in a small package and has a wide operating temperature range making it suitable for a wide range of applications. The device also has ESD immunity of up to ±12 kV Human Body Mode for improved reliability and tolerance to electrostatic discharge, and a ruggedized leadless design with an industry-standard SMD solder joint for fast installation.
