TVS - Varistors, MOVs are diverse protective components for electronic circuits and power systems designed to clamp down, diverting surge current away from sensitive devices. Among these components, V385LS20CPX2855 is a highly successful protective element.

V385LS20CPX2855 is a bistable PN junction device with an Anti- transient pulse clamp capacitor, which has the characteristics of high current stand-off voltages combined with the self-healing feature of an MOV.

The application field of V385LS20CPX2855 is widely varied from low voltage communication lines to high voltage industrial control systems such as voltage sensitive ICs, cables, I/O cards, relays and microprocessors, as well as power supplies, servers, computers and IT applications.

The working principle of V385LS20CPX2855 is corresponding. It uses its built-in coupling capacitor to reduce the voltage level of the transient surge and thereby restricting the voltage applied to the protected circuit. The threshold voltage of the device is factory pre-set, and when the incoming transient voltage exceeds this threshold, the V385LS20CPX2855 will clamp the voltage through the clamp capacitor and dissipate the surge current through its external power resistor. The transistor action of the device will disconnect the surge from the protected components until the transient is reduced to a safe level. This self-resetting feature allows for a cycle of surge protection without the need to reinstall the component.

Additionally, the V385LS20CPX2855, thanks to its high peak current and broad operating temperature range, is also effective in providing ESD protection. It is used to limit the voltage on a particular line or circuit, acting as a fast triggerable clamp to protect electronic equipment from Electrostatic Discharge (ESD) damage.

V385LS20CPX2855 also has many other advantages, such as the ability to operate at a wide AC/DC voltage rangewithout significantly reducing its level of protection, and a proprietary film capability that helps ensure better current-limiting performance.

To conclude, V385LS20CPX2855 is an ideal protective element for all sorts of electronic devices and power systems. Its application field is varied and its working principle is a low reverse leakage current combined with a unique triggering action. Its power resistor dissipates the surge current and its self-resetting feature makes it an attractive choice for effective ESD protection for a wide variety of components.
