Transient voltage suppressors (TVS) are a type of diode which is used to protect electrical and electronic components from voltage spikes. The SMCJ36A V7G is a TVS diode designed to protect electric components from transient voltage and current spikes due to events such as electrical surges, electrostatic discharge, lightning strikes, and switching or electromagnetic interference (EMI).

This diode is a popular choice for its quick response, low leakage current, and low capacitance. Designed for medium voltage applications, the SMCJ36A V7G has a reverse stand-off voltage of 36V and a power dissipation of 720W. It has a peak pulse power of 20000W and a peak surge current of 55A. The maximum clamping voltage is 57.7V.

The SMCJ36A V7G is typically used in low-voltage networking, communication, and computer devices. Common applications include communications lines, USB data lines, terminal equipment, and serial and parallel ports. It is also used in solar power systems and in electric and hybrid-electric vehicles.

In order to understand how this diode works, it is important to understand the basics of diode operation. Diodes are comprised of two terminals called an anode and a cathode. In a circuit, current flows from the anode to the cathode when a voltage is applied to the diode. In a reverse-biased situation, no current can flow and the diode becomes an open circuit, allowing no current to flow.

The TVS diode works by limiting and diverting current when the reverse bias voltage exceeds the TVS reverse stand-off voltage. This event causes the diode to become forward biased, allowing current to flow from the anode to the cathode and limiting the current to safe levels. The current-limiting capability of the TVS diode is especially useful in applications where large voltages and currents may be present.

The SMCJ36A V7G is specially designed to protect sensitive electronic circuits from large voltage transients. It has an extremely fast response time, allowing it to react quickly to events such as ESD strikes or lightning, minimizing the potential for damage. The low leakage current and low capacitance allows for better protection of sensitive components. The TVS diode is also designed to dissipate relatively large amounts of energy when needed and to reset quickly after an overvoltage condition has been resolved.

In summary, the SMCJ36A V7G is a popularly used TVS diode designed to protect electric components from transient voltage and current spikes due to electrical surges, electrostatic discharge, lightning strike, and EMI/RFI interference. Its response time, low leakage current, and low capacitance combine to make it an ideal choice for a variety of applications such as networking, communications, computer devices, and solar power systems.
