TVS (Transient Voltage Suppressor) Diodes are essential for suppressing electrical spikes that may occur in electronic products. The MP5KE120CA is one such device, designed to provide protection and prevent circuit damage from overvoltage transients such as electrostatic discharges (ESD).

The MP5KE120CA is constructed of a bidirectional breakover diode in a dual-in-line flat leaded package (FLP). It has a Peak Pulse Power of 600W for an 8/20µs surge current and its clamping voltage is rated at 120V. It also has a low leakage current of <1µA max. That makes it suitable for a variety of applications where overvoltage and ESD protection are important.

The MP5KE120CA is primarily used in commercial electronic equipment that requires high immunity to ESD strikes and fast response times. It protects against static electricity and power surges, often on communication components such as telephone lines, network equipment, data lines, and consumer electronics. It can also be used on AC power lines for sensitive equipment such as variable frequency drives (VFDs) as well as consumer microcontrollers.

The working principle of the MP5KE120CA is that when a voltage above the nominal clamp voltage is applied, it breaks forward until the applied voltage is dropped to a lower level. This process is known as avalanche breakdown. The internal diode avalanche junction absorbs the excessive energy in the form of heat, while providing a low resistance path that redirects the voltage to ground.

Once the voltage is reduced to a safe level, the MP5KE120CA will reset itself to its original condition and is ready to protect against further transients. The device is designed to provide superior protection with a fast response time and low capacitance. It is one of the most versatile transient voltage suppressors on the market and perfect for protecting sensitive electronic components from ESD and other damaging voltage transients.
