Varistors, MOVs, and TVS (transient voltage suppression) are useful components in electrical circuits. These components are used to protect against electrical surges caused by lightning, power outages, and other disturbances in the electrical grid. The VE13P00231K is a TVS component specifically designed to protect circuit components from harmful electrical spikes.

VE13P00231K Description and Application Field

The VE13P00231K is a bidirectional TVS diode designed for transient voltage and ESD (electrostatic discharge) protection. It is encapsulated in a SOD-123 epoxy-free package that is RoHS compliant and aqueous-processable. It works over a wide temperature range from -40°C to +150°C and is designed for industrial, automotive, and LED lighting applications.

The component\'s features enable it to provide robust protection against ESD (electrostatic discharge) exposure up to 15kV requirements, as well as comply with IEC 61000-4-2 Level 4 standards. It is also capable of discharging large transient pulses up to 8A, and its low capacitance ensures fast response time.

VE13P00231K Working Principle

The VE13P00231K works by using a Zener voltage that is sandwiched between two metal-oxide layers. At normal levels, the Zener voltage is greater than the clamping voltage of the metal-oxide layers. This prevents the current from moving through the TVS diode. However, when a surge occurs, the Zener voltage breaks down and the current is allowed to move through the metal-oxide layers, thus routing the surge away from the circuit. This is why TVS diodes are often called surge protectors.

In addition to providing protection against electrical surges, the VE13P00231K is also designed to provide strong electrostatic discharge protection. This is because the Zener voltage of the TVS diode is designed to absorb and dissipate excessive electrical energy. This helps to protect components from damage caused by sudden spikes of high voltage.

The bidirectional feature of the VE13P00231K also allows it to monitor and protect the circuit in both directions. This increases its protection capabilities as it can address ESD events from multiple directions. This ensures that the system is not only protected from high voltage transients, but also from sudden, damaging electrostatic discharges.

Conclusion

The VE13P00231K is a bidirectional TVS diode designed for ESD and transient voltage protection. Its features enable it to withstand large transient pulses up to 8A and ESD events up to 15kV, as well as offer fast response time. In addition, its bidirectional feature allows it to monitor and protect the circuit from multiple directions. This makes it an ideal choice for industrial, automotive, and LED lighting applications.
