TVS (Transient Voltage Suppressor) diodes are components used to protect circuits from potentially harmful voltage transients. The SMLJ200CE3/TR13 is a unidirectional TVS diode device designed for high power transient protection in applications such as networking, video, industrial, telecommunications, and broadband systems. In this article, we will discuss the application field and working principle of the SMLJ200CE3/TR13 TVS diode.

Application Field of SMLJ200CE3/TR13 TVS diode

The SMLJ200CE3/TR13 is a low capacitance, high reliability TVS diode suitable for a wide range of applications due to its robust construction and low capacitance. It is ideally used in high speed signal protection circuits for communications, electronics, industrial, and automotive devices. It is also widely used as a power supply and data line protection device, for example in motor control devices, data lines, power supply lines, and other areas that require robust ESD protection.

The SMLJ200CE3/TR13 is a low capacitance, fast response, unidirectional TVS diode with a peak pulse power rating of 200 Watts, a breakdown voltage of 13 Volts, and an operating temperature range from -55 to 150 degrees Celsius. The device features a low leakage current for higher reliability during use, and the low capacitance is especially well-suited for improving the signal integrity of high speed applications.

Working Principle of SMLJ200CE3/TR13 TVS diode

The working principle of the SMLJ200CE3/TR13 TVS diode is based on the PN junction theory, which states that when a voltage is applied across a PN junction diode, an electrical current will flow through it. The voltage at which current begins to flow is known as the threshold voltage, or breakdown voltage. This is the voltage at which the diode starts to conduct.

The SMLJ200CE3/TR13 is a unidirectional TVS diode, meaning that it will only conduct current in one direction. If the applied voltage exceeds the device’s breakdown voltage, then the diode will conduct the surge current for a short period of time, allowing only a limited amount of voltage to pass through. This prevents the circuit from being damaged by excessive surge voltage.

The SMLJ200CE3/TR13’s peak pulse power rating of 200 Watts indicates that it can handle up to 200 Watts of peak pulse power, which is typically achieved during a surge event. The device also has a low capacitance, meaning that it does not affect signal integrity if it is placed across high-speed applications, providing added protection without affecting the quality of the signal.

The SMLJ200CE3/TR13 is a robust and reliable TVS diode with wide ranging applications. It is designed to protect against ESD transients, and to provide temporary surge protection without affecting the signal integrity of high-speed applications. Its low capacitance and peak pulse power rating make it a great choice for a variety of applications.
