The SMCJ26CE3/TR13 is a breakdown diode that belongs to the transient voltage suppressors (TVS) series. The device is available in a discrete, SMC-SMD, SMA, 3QFN, DPAK, TSOP, and EPD packages, and is designed to protect against electrostatic discharge (ESD) and transient voltage induced electrical surge events.

These diodes are designed to protect components by clamping transient voltages to specific peak levels. It is a bi-directional device with symmetrical ESD protection, featuring a maximum breakdown voltage of 28 volts. As with other breakdown diodes, the SMCJ26CE3/TR13 has a junction impedance which increases exponentially-drop with the increase of overload voltage.

The SMCJ26CE3/TR13 can handle sub-microsecond and nanosecond transients, such as EFT, ESD, and ISO 1146 COMPLIANT with the HBM peak voltage of 30kV and maximum clamping voltage of 28V. It has a very low working power dissipation, with a high surge protection and a low capacitance. The device also features high speed EMI filtering and transient protection, making it ideal for portable and data processing applications. The device also has excellent surge current endurance with an absolute maximum of 28,000 amps.

The SMCJ26CE3/TR13 is typically used in high speed data processing and telecommunications equipment, LCD displays, computer systems, and consumer electronic equipment. This breakdown diode can also be used to protect other components from electrical overvoltage, including sensors and microprocessors. The device can also be used in DC and AC power supply lines as a surge protector. It is designed to clamp voltages above its breakdown voltage, in order to limit any overvoltage.

The working principle of the SMCJ26CE3/TR13 is similar to other breakdown diodes, and it is based on the process of the depletion layer. When the voltage across the diode exceeds the breakdown voltage, the depletion layer passes large currents, and then the breakdown occurs. The SMCJ26CE3/TR13 is a bipolar device, so it has two junctions, and the breakdown voltage is the sum of both. This diode is also very resistant to EMI, making it an ideal choice for high-frequency applications.

The SMCJ26CE3/TR13 is a versatile breakdown diode that is suitable for a wide variety of applications. With its high surge protection, low working power dissipation, low capacitance, and excellent EMI protection, it is ideal for protecting components from transient events. It is an ideal solution for data processing applications, electronic equipment, and power supply lines.
