TVS diodes are essential components in a variety of electronic applications. SMCJ85CA-13 is a member of that family. It is a unidirectional TVS diode designed for ultra-high-speed transient protection. It can withstand voltages up to 130V and suppress up to 15,000 W of power.

The main application field of SMCJ85CA-13 can be found in the automotive and industrial sector. It is a valuable device to protect automotive electronic components such as microcontrollers, sensors, switches and motor control systems from transients. In addition, it is designed for medical application, telecommunication, consumer electronics and other high integrity applications where transients occur.

The device works according to the principle of avalanching current, which is a phenomenon that occurs when the diode junction is exposed to a potential greater than its PIV. When the voltage rise is within the avalanche region, the power dissipation along the junction increases sharply, which results in a bigger current that rapidly rises and is then discharged.

When the avalanche is triggered, current begins to flow in a reverse direction, quickly becoming a very small voltage pulse. This pulse is then dissipated on an external load. Due to its low leakage and high capacitance characteristics, SMCJ85CA-13 is an excellent choice for high frequency protection applications.

Furthermore, the SMCJ85CA-13 has a fast response time and can protect components from the latch-up effect. This effect occurs when a large current flows through the integrated circuit, causing it to malfunction or become damaged. With this device in place, the sensitive components are completely protected.

The SMCJ85CA-13 is also designed to provide excellent heat dissipation, allowing for a higher current capability than other TVS devices. It is packaged in a very small package, making it easy to install in the tightest spaces. Additionally, it has superior electrical characteristics and is RoHS compliant.

In conclusion, SMCJ85CA-13 is a reliable diode designed to provide excellent transient protection while offering excellent electrical and thermal characteristics in a small package. It is ideal for applications such as automotive, medical, telecommunication, consumer electronics and more, where transients need to be controlled and lower power dissipation is necessary.
