TVS - Diodes

TVS-diodes are semiconductor devices designed to provide protection against electrical transients and high-frequency noise.

M5KP43CAE3 Application Field and Working Principle

The M5KP43CAE3 is a 4.7V and 5.6V bidirectional transient voltage suppressor (TVS) diode designed for protecting sensitive electronics from voltage spikes and transients caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. It is a plug-in type component that provides superior surge protection.

The M5KP43CAE3 is designed to meet the IEC 61000-4-2 standards for ESD immunity and can handle electrostatic discharges up to 28kV air discharge and 8kV contact discharge.

It is an industry-standard component designed for use in HVAC/R appliances, industrial systems, computers, peripherals, data lines, and consumer electronics. The device can also be used in automotive applications to protect against power surges.

The M5KP43CAE3 works by allowing normal currents to pass in both directions through the diode while preventing transients and other forms of overvoltage. The device is a Bidirectional TVS diode, which means it can absorb ESD on both the positive and negative side. The device has a fast response time and can clamp the voltage to any level below the breakdown voltage within a few nanoseconds. This prevents the electrical spikes and transients from damaging sensitive components.

The M5KP43CAE3 is constructed from an anode and a cathode, which are connected to ring shaped electrodes. A thin oxide layer separates the anode and cathode. When a transient spike in voltage occurs, the oxide layer breaks down and current flows from the anode to the cathode. This clamps the voltage at any level below the breakdown voltage and prevents the spike from damaging sensitive components.

The M5KP43CAE3 is a compact, robust, and cost-effective solution for protecting sensitive electronics from voltage spikes and transients. It is a reliable and easy to install component that can provide superior surge protection.
