TVS (Transient Voltage Suppresor) Diodes are components made up of a Zener diode combined with a P-N junction diode. SMCJ28CE3/TR13 is one of the most popular value-priced diodes widely used for transient voltage clamping.

TVS Diodes are devices designed to protect sensitive electronic components from high voltage transients, like ESD (Electrostatic Discharge) and secondary voltage transients in switching power supply and power line applications. The device is ideal for precious consumer electronics, communication and industrial application fields with an operating temperate of -55°C to 150°C.

The SMCJ28CE3/TR13 diode is tailored for protecting against the effects of ESD and high-energy transients. It covers a wide range of ESD and transient voltages, and its ESD protection exceeds the Human Body Model (HBM) levels of IEC61000-4-2. The SMCJ28CE3/TR13 is suitable for a wide range of applications, such as computers, telecom and network equipment, and embedded systems.

The main advantage of using the SMCJ28CE3/TR13 is its low breakdown voltage of 28V and low leakage of 1.2mA at 25°C. It also features a low capacitance of 75pF at 1MHz (typical) and low clamping voltage of 39V at 8A. Its excellent ESD capability makes it ideal for almost any high-speed interface applications. Additionally, the diode has a wide operating voltage of 5V to 28V and an operating temperature of -55°C to 150°C.

The working principle of the TVS diode is quite simple. When a high-voltage transient is encountered, the TVS diode will clamp the voltage supply at the breakdown voltage of the diode. This prevents the voltage from exceeding its maximum voltage rating. It also provides ESD protection by quickly clamping high voltage ESD transients before they can cause permanent damage to the device. Thus, TVS diodes are an effective and reliable protection device for any electronic equipment.

In summary, the SMCJ28CE3/TR13 diode is an excellent value-priced diode, designed for a wide range of applications. It features a low breakdown voltage of 28V and low leakage of 1.2mA at 25°C. It also has a wide operating voltage of 5V to 28V and an operating temperature of -55°C to 150°C. The diode provides superior ESD protection, exceeding the Human Body Model (HBM) levels of IEC61000-4-2. Finally, the working principle of the TVS diode is simple in that it prevents voltage from exceeding its maximum voltage rating with the aid of a clamping voltage. All these features make the SMCJ28CE3/TR13 the ideal choice for any electronic equipment requiring high-performance protection from high-voltage transients.
