SMDA15CE3/TR13

Transient Voltage Suppressors (TVS) diodes are electrical components designed to protect circuits from voltage spikes. The SMDA15CE3/TR13 TVS diode is designed specifically to protect against 15V transients, and this article will explain the application field and working principle of this component.

Applications

The SMDA15CE3/TR13 TVS diode is rated for a standoff voltage of 15V with a maximum breakdown voltage of 30V and maximum peak pulse power of 600W. It has a low Clamping Voltage (V_C) and a maximum Clamping Voltage of 24V.

The SMDA15CE3/TR13 is ideal for use in consumer electronics and automotive applications. It can be used to protect against electrostatic discharge (ESD) on communication ports, high voltage transients on power lines, and surges on data lines in automotive applications. Additionally, it can also be used for protection against overvoltage transients in industrial applications.

Working Principle

The working principle of SMDA15CE3/TR13 is based on the avalanche breakdown of a PN junction. When the applied voltage reaches the breakdown voltage of the PN junction, the depletion region of the junction expands exponentially, allowing a large amount of current to flow. This current flow causes a voltage drop across the component, which is known as the Clamping Voltage (V_C).

The SMDA15CE3/TR13 is designed to provide protection against high voltage transients. When a transient voltage spike is applied, the PN junction in the component will conduct current, which causes the Clamping Voltage (V_C) to drop, dissipating the energy of the transient. This limits the voltage and current that can be applied to the protected circuit, preventing any potential damage.

Conclusion

The SMDA15CE3/TR15 is a TVS diode designed to protect against 15V transients. It has a low Clamping Voltage (V_C) and is ideal for consumer electronics and automotive applications. The working principle of the component is based on the avalanche breakdown of a PN junction, which is used to dissipate the energy of transient voltage spikes and limit the voltage and current that can be applied to the protected circuit.
