V385LA20CP is a type of transient voltage suppressor (TVS) device. It is designed to protect sensitive electronic equipment from transient voltage spikes, also called transients. Transients can cause damage to sensitive electronic components due to their extremely short duration and high energy. The V385LA20CP is a metal oxide varistor (MOV) device, which is a type of TVS. MOVs are typically used for power line transient voltage surge protection applications.

The V385LA20CP features a dielectric strength rating of 2500V AC, a surge current rating of 200A, and an operating temperature range of -55°C to 125°C. This device offers high surge current protection and low-clamping voltage, enabling it to effectively suppress large transients. It also offers good ESD protection and is capable of damping high dV/dt spikes. The device is well suited for protection against lightning-induced surge and line-to-ground transients.

V385LA20CP devices are commonly used in a variety of applications, including industrial equipment, medical devices, power supplies, automotive electronics, and consumer electronics. The device has a wide operating temperature range, high pulse current ratings, and low peak-to-peak capacitance values making it ideal for automotive applications. It is also UL1449 approved for industrial applications.

The working principle of the V385LA20CP is based on the functioning of a MOV. It functions like a resistor, with its resistance varying depending on the voltage applied to it. The MOV connects across two electrodes of a circuit. When a current spike passes through the circuit, the MOV absorbs the voltage and transfers it to a secondary sink, such as a ground, thereby preventing the voltage from reaching any sensitive components in the system.

The V385LA20CP has a high rated surge current capability. When the device absorbs a surge current, it’s resistance increases, allowing it to reduce the voltage to harmless levels. If the surge current is too great, the device will be destroyed, but the shock is reduced to a safe level. This ensures maximum protection for the system.

The V385LA20CP is a versatile and reliable device that can handle both high voltage and high current transients. It can be used in a variety of applications, including industrial equipment, medical devices, power supplies, and automotive electronics for its surge protection capability.
