TVS diodes are widely used for ensuring the protects of any electronic system from transients, the SMAJ180A-H is not an exception. This component has an ultra-fast response time that makes it a great choice in protecting several applications from surges, spikes, electrostatic discharges, and other disruptive phenomena.

The SMAJ180A-H is a bidirectional unidirectional transient suppressor mounted in a sealed SMB package with a fast response time. The device is composed by a special diode array network and transient energy absorption components that are designed to provide superior protection from high energy transients into the data or power line.

The SMAJ180A-H stands out from the other TVS diodes because it is capable of sustaining voltage up to 178V without any additional elements, which provides enhanced protection against over voltage transients in LAN and ISDN applications, equipment controllers or other similar applications.

Furthermore, the working principle of the SMAJ180A-H consists in absorb transients when exceeding the limit of this voltage by relying in the avalanche breakdown of the diode. This working is based on a steep power versus voltage curve of the diode that allows transients to be clamped in high voltage situation to the breakdown limit, preventing disruption in the voltage level in the system as it is seen in figure 1.

The SMAJ180A-H is a great choice for offering protection from transient dropouts in any communication, control or industrial equipment. The device supports transients up to 1500W of peak pulse power and a peak pulse current of 83A in a 10/1000µs pulse width waveform.

This TVS diode can be used in different types of industrial applications, such as power electronics, telecom, computer systems, consumer electronics, electrical components, automotive systems. Some of the applications that could take advantage of the SMAJ180A-H include power supplies, printed circuit boards, relay drivers, motors, heaters, controllers, and other similar uses.

The SMAJ180A-H is an excellent option to protect systems from transients that can cause electrical malfunctions that would lead inadequate performance or serious breakdowns. That is why this product is widely used in electronics industry because of its reliable protection, low capacitance and low leakage current characteristics.
