TVS Diodes

MX15KP120AE3 Application Field and Working Principle

Transient Voltage Suppressors (TVS) diodes are a special type of electronic component that, when a voltage exceeds a certain level, can conduct current and protect a circuit from further damage. This makes them a key component in power electronic applications, such as automotive, industrial, medical, and aerospace. The most common type of TVS is the unidirectional (unipolar) type, which consists of a single junction diode with a reversed breakdown voltage.

The MX15KP120AE3 is a unidirectional TVS diode that protects against electrostatic discharges. The reverse breakdown voltage of the MX15KP120AE3 is 15 kV, making it ideal for protecting sensitive electronic components from electrostatic discharges (ESD). The MX15KP120AE3 also features an "active shield" that absorbs most of the energy from an incoming ESD pulse before it breaches the specified breakdown voltage.

The MX15KP120AE3 has a wide operating temperature range from -55°C to 125°C and is capable of dissipating up to 500 Watts of power. It has an insulation voltage of 10 kV, making it suitable for special purpose and telecom applications. Furthermore, its fast response time makes it suitable for a number of signal line protection applications.

In operation, TVS diodes protect electronic components by absorbing excessive voltage or current and then effectively blocking further current flow in the circuit. They do this by forming a low resistance electrical pathway that can quickly and safely absorb high energy transients. When the current of the incoming pulse is below a specified level, the diode does not conduct and the external component is protected from further damage.

The MX15KP120AE3 is designed specifically to protect against ESD pulses, and its active shield will absorb most of the energy from the pulse before it breaches the specified breakdown voltage. The diode\'s fast response time ensures that it can react quickly to incoming pulses and protect sensitive components from further damage or interruption.

The MX15KP120AE3 is an ideal TVS diode for applications that require ESD protection, rapid response time, and high power dissipation. Its wide temperature range and insulation voltage make it suitable for a variety of applications, including power control systems, telecommunications, and automotive EMC systems. With the ability to absorb and dissipate high amounts of power, the MX15KP120AE3 is an effective solution for protecting sensitive components from ESD pulses.
