V460LT40BPX2855

TVS (Transient Voltage Suppressors) are protection devices used to protect sensitive electronic equipment from transients and other high voltage pulses caused by lightning, short circuits, and electrostatic discharges. Varistors, MOVs (Metal Oxide Varistors), and other components are used as TVS protection devices. Varistors are very effective in controlling transients and are used widely in various applications. The V460LT40BPX2855 is one such varistor.

The V460LT40BPX2855 is a bidirectional, non-linear voltage clamping, and over-voltage protection device with 9pF capacitance and 40V peak pulse power. It is a metal-oxide varistor (MOV) that provides fast response to transient overvoltages. It has a wide operating temperature range of -40 °C to +125 °C and is rated for current up to 1kA. The V460LT40BPX2855 is typically used in SMPS applications, automotive applications, motor-control circuits, and EMC (electro-magnetic compatibility) applications.

The working principle of the V460LT40BPX2855 involves a combination of dynamic and static over-voltage protection. It has a bidirectional, non-linear voltage clamping design that enables it to “clamp” voltage surges and transients to a safe value. This prevents the connected electronic components from being damaged due to over-voltage spikes. This clamping function is achieved by a metal-oxide layer which acts as a variable resistor and effectively maintains the voltage below a certain threshold value. The V460LT40BPX2855 also has a high-frequency bypass capacitor that helps absorb high-frequency transients and prevents them from affecting the connected circuit.

In addition, the V460LT40BPX2855 provides ESD (electrostatic discharge) protection to prevent static electricity from damaging connected components. It also offers high surge current protection and eliminates false triggering of the MOV due to high-current pulses. This ensures that over-voltage protections are effectively implemented in the system.

The V460LT40BPX2855 is an ideal device for protecting sensitive electronic components from transient voltages and ESD, and is suitable for use in various industrial, automotive, and consumer applications. It is easy to use, cost-effective, and provides reliable over-voltage protection.
