TVS (transient voltage suppressor) diodes are widely used and are important components in a wide variety of electrical and electronic systems. SMBJ85C-E3/52 is a unidirectional bi-directional transient voltage suppressor diode that can be used in various systems including automotive, telecommunication, consumer electronics and industrial systems. This diode is capable of withstanding high transients such as those caused by electrical drives, power-line spikes, short circuits and surge currents.

The SMBJ85C-E3/52 TVS diode is primarily designed to protect components from over-voltage transients. It is constructed by forming two back-to-back junctions in a single package. The two junctions are arranged to handle reverse bi-directional transients, meaning that the diode will clamp the voltage at both positive and negative transient peaks. This type of diode offers high protection, short clamping time and excellent surge capability.

The SMBJ85C-E3/52 TVS diode is available with a breakdown voltage rating of 7V to 84V. This diode can withstand high pulse current up to 1.5KA peak for a 10/1000simpulse (TP5). The diode is designed for unidirectional reverse bi-directional transient voltage protection. The diode also has an operating temperature range of -65℃ to +175℃.

The working principle of this diode is relatively simple. When a voltage transient passes through the diode it causes the diode junction to become higher than the breakdown voltage. The diode will then clamp the voltage at the breakdown voltage. This is why the TVS diode is often referred to as a “clamping” diode. The diode will keep the voltage at the breakdown voltage until the transient has passed. The diode will then return to its original voltage state.

In various applications, the SMBJ85C-E3/52 TVS diode can be used as an overvoltage protection device. It can be used in automotive systems to protect components from voltage transients caused by ignition, misfiring or switching inductance. The diode can also be used in consumer electronics to protect electrical circuits from sudden voltage spikes. The diode can also be used in industrial systems to protect components from high electrical surges.

TVS diodes play an important role in protecting circuit components from damage caused by voltage transients. The SMBJ85C-E3/52 TVS diode offers excellent surge and over-voltage protection, making it ideal for a wide variety of applications. It is a robust and reliable device that can be used in automotive, telecommunication, consumer electronics and industrial systems.
