The SMCJ28E3/TR13 is a bidirectional single line low-capacitance transient-voltage-suppression diode. It is mainly used for the protection of the equipment from the transient overvoltage and ESD. The device is designed to provide a very fast response time along with a low operating capacitance of 28pF.

As a diode, the primary working principle of the SMCJ28E3/TR13 is that it acts as a switch, meaning it can pass the current in either direction across the circuit, or acts as a short circuit when the undesired transient voltage occurs. It is made of a semiconductor material as the junction of two different type materials, one is P material (positive) and another one is N material (negative). If the polarity is given to the P pole, the electrons are attracted to the p material and hence the diode is in ON state, and when the opposite polarity is given to the P material, the electrons are repelled and the diode is in OFF state.

The application field of the SMCJ28E3/TR13 mainly includes industrial, automotive and consumer applications. It is capable to suppress very fast transients with a peak pulse power rating of 600 W at 10/1000 µs. It can also work at a wide operating temperature range of -55°C to +150°C. Due to its wide temperature range, the SMCJ28E3/TR13 is used in communication systems, instrumentation and vehicle control systems to protect against overvoltage transients. Also, it is used in industrial-control circuits, I/O circuits and power lines.

The SMCJ28E3/TR13 is widely used for providing protection from the transient overvoltage and ESD. Its bidirectional design and low capacitance make it useful for protecting sensitive circuits. It has a low-clamping voltage and a very fast response time of less than 1 nanosecond due to which it is suitable for a wide variety of applications. In addition, it is RoHS compliant and has integrated ESD protection.

In summary, the SMCJ28E3/TR13 is a bidirectional transient-voltage-suppression diode. It is mainly used to protect equipment from the transient overvoltage and ESD. It has a very low capacitance and a wide operating temperature range. It is used in industrial, automotive and consumer applications due to its high peak pulse power rating and fast response time. It is RoHS compliant and provides integrated ESD protection.
