Transient Voltage Suppressor (TVS) diodes are used to protect circuitry from over-voltage transients. These over-voltage transients can arise due to lightning strikes, load shedding, and other power supply disturbances. The SMCJ200CE3/TR13 is an ideal device for applications where the over-voltage protection range needs to be increased due to high signal voltages or redundant protection against voltage spikes.

The SMCJ200CE3/TR13 is a unidirectional TVS diode with a 2.5 kV breakdown voltage, and a VBR of 6.0 V. It has a maximum peak pulse power rating of 200 Watts with a 10/1000μs pulsewidth. The device features a low capacitance of 0.6 pF which makes it suitable for high-speed communications circuits such as USB ports, telecom ports, and Ethernet ports. The SMCJ200CE3/TR13 also features an ultra-low low-clamping voltage which ensures system stability in the presence of transient over-voltages.

The device operates in two modes. The first mode is the absorption mode, which is when the over-voltage transient is clamped. The absorption mode occurs when the voltage spike exceeds the VBR of the device. The second mode is the recovery mode, where the SMCJ200CE3/TR13 allows the voltage to return to normal levels slowly. This is done to prevent any further damage to the circuitry.

The SMCJ200CE3/TR13 TVS diode is optimally designed for use in applications such as automotive, home appliances, consumer electronics, industrial, and telecom/datacom equipment. For automotive applications, the SMCJ200CE3/TR13 provides reliable over-voltage protection for input terminals of electronic control units and other electronic components. In home appliances, the device can be used for protection against power surges from dishwashers, washing machines, and other appliances. In telecom/datacom applications, the device can be used as an effective protection device against voltage surges from ESD and power-line bursts.

These devices are also useful for providing transient over-voltage protection in industrial systems. They can be used to protect the circuitry from voltage spikes in programmable logic controllers, remote terminal units, and motor drives, which can be affected by the induction of large conductors.

To conclude, the SMCJ200CE3/TR13 TVS diode is a reliable device for providing over-voltage protection in a wide variety of applications. It offers a low capacitance, high peak pulse power rating, and an ultra-low clamping voltage, which makes it ideal for high-speed communications and other over-voltage protection circuits. The device offers two operating modes, the absorption mode and the recovery mode, which ensures system stability in the presence of transient over-voltages.
