The SMDA12C-7/TR7 is a unidirectional TVS diode, specifically designed to protect sensitive electronic devices from high voltage spikes or surges. It has the ability to protect against transients caused by lightning, AC Line, DC or any other form of energy. The SMDA12C-7/TR7 is designed with Zener technology, which is a cost-effective way to protect vulnerable electronic components. The SMDA12C-7/TR7 has superior clamping protection and fast response time, which make it an ideal choice for protecting sensitive electronic equipment.

The SMDA12C-7/TR7 has its unique design structure which includes two metal-oxide-semiconductor structures, mounted to a PCB. One of them is an N-type MOS, and the other is an P-type MOS. The two MOS structures are connected in series to form an avalanche diode. The structure of the SMDA12C-7/TR7 consists of a pair of a low power (gate) transistor and a high power (drain) transistor, all bonded together on a single layer substrate.

The working principle of the SMDA12C-7/TR7 is based on the Zener-Breakdown or Zener-Aviation principle. When a high voltage is applied to the anode of the diode, the electrons in the low power MOS structure will begin to flow very rapidly. If the voltage exceeds the breakdown voltage of the device, the electrons will be accelerated to near light speed, and trigger an avalanche effect across the PN junction. This avalanche effect causes the diode to enter the breakdown region. The result is that the diode will clamp the voltage on its output terminals to a safe level. This prevents dangerous spikes from damaging sensitive electronic components.

The SMDA12C-7/TR7 is commonly used in a wide variety of applications. The most common applications include laptop computers, hard disk drive enclosures, wireless devices, and other sensitive electronic components. It is also used as a line clamp regulator in surge protector applications. It is especially effective in applications where high voltages are present such as wire-clamp, automotive, and medical applications.

The SMDA12C-7/TR7 is built with highly reliable construction, and is designed to withstand various environmental conditions. It is capable of handling transient voltage spikes up to 2000 volts. It includes an integrated line regulator, which helps to reduce losses and minimize EMI emissions. The SMDA12C-7/TR7 is RoHS and Lead Free compliant, making it an ideal choice for consumer applications.

The SMDA12C-7/TR7 TVS diode is a highly reliable device, designed to protect sensitive electronics from high voltage spikes and surges. It is a smart choice for applications where a fast response time and effective voltage clamping is required. Its robust design and superior clamping protection make it a perfect fit for a wide range of applications.
