TVS diodes are a class of diode arrays used to provide transient overvoltageprotection in alternative current (AC) or direct current (DC) power circuits. Among these various diodes, SMAJ110CA-M3/61 is a popular choice for its wide voltage range and low leakage current. Manufacturers around the world have seen the growing need for reliable, robust and cost-effective solutions for protecting power circuits. This article will explain the application field and working principle of the SMAJ110CA-M3/61 TVS diode.

Application Field

SMAJ110CA-M3/61 TVS diode can be applied in a range of applications including AC/DC power circuits, rechargeable battery protection, and communications-related applications. For AC/DC power protection, the diode offers a wide working voltage range from 5 to 180 volts. Additionally, it has a low clamping voltage of 8.7volts, maximum peak pulse power dissipation of 1500W and 97A peak pulse current.

In terms of communications applications, SMAJ110CA-M3/61 TVS diode can be used for protection of sensitive electronic equipment from ESD/EMI/RFI/transient overvoltage. It has a 200 watt peak pulse power dissipation and is designed to provide protection from transients such as lightning and static electricity.

Another application of the SMAJ110CA-M3/61 TVS diode is rechargeable battery protection, offering a voltage range from 5 to 30 volts and a maximum peak pulse power dissipation of 500 watts. For this application, the diode is designed to protect the battery from overvoltage and out-of-spec currents.

Working Principle

The SMAJ110CA-M3/61 TVS diode works as an overvoltage protection device. It is capable of absorbing high-energy transients such as electrostatic discharges, lightning bolts, surges, and overvoltages caused by inductive loads in AC power circuits. The diode is composed of an anode, a cathode and a PN junction.

When there is an overvoltage event on the power supply, the TVS diode will be triggered. Its PN junction will become forward biased, allowing current to flow, and the diode will absorb the excess energy. The absorbed energy is then dissipated in the form of heat, providing protection for the power supply and the connected components. The TVS diode will then return to its reverse-biased state after the transient overvoltage event is over.

In summary, SMAJ110CA-M3/61 TVS diode is an effective overvoltage protection device used in an extensive range of applications from AC/DC power circuits to rechargeable battery protection and communication equipment. It is designed to provide reliable protection against transients such as lightning and static electricity, and its working principle is based on its PN junction, which is triggered when an overvoltage event occurs and absorbs the excess energy.
