The V140LA5P is a type of transient voltage suppression (TVS) device, specifically a varistor. Varistors, sometimes called vibrationally induced breakdown suppressors (VIBDs), are voltage-dependent, nonlinear resistors designed to protect against voltage spikes and surges. Varistors provide over-voltage protection for both AC and DC lines, and can also limit out-of-tolerance voltages. They are available in many shapes and sizes, ranging from surface-mount devices to large power blocks.
Varistors are non-linear devices that act like a diode whose resistance changes depending on the applied voltage. At normal operating voltages, the varistor\'s resistance is high, blocking or limiting low-voltage signals from passing through. As the input voltage increases, the resistance of the varistor decreases. When it reaches a certain critical voltage, known as the breakdown voltage, the varistor becomes highly conductive, allowing large currents to pass through it and then quickly dissipate the energy. This is known as clamping, and it is essential for providing effective protection against voltage spikes.
The V140LA5P is a 5.2A, 140V, low-capacitance TVS diode. It has a low capacitance of 0.1pF, making it ideal for fast-switching applications. The diode also features an internal EMI filter for more efficient noise suppression. The device also features thermal runaway protection to help prevent damage due to overheating. The V140LA5P is RoHS compliant and UL recognized, meaning it meets the safety standards for use in industrial and consumer applications.
The V140LA5P is used to protect circuit boards, components, and other devices from over-voltage and transient events. It can be used in both AC and DC applications, as well as both in-line and surface-mount configurations. The V140LA5P is often used in appliance and automotive electronics, as well as audio and video equipment. It also has various other industrial applications, such as data line protection, communication systems, machine tools, and medical equipment.
The working principle of the V140LA5P is simple. When the voltage across its terminals exceeds its breakdown voltage, the varistor becomes highly conductive. This allows large currents to flow through it and quickly dissipate the energy from spikes. The device also has thermal runaway protection, which helps to prevent damage due to overheating. The device can be used in both in-line and surface-mount configurations, providing effective protection against over-voltage and transients.
