TVS - Diodes

TVS - or transient voltage suppressor - diodes are semiconductor devices deployed to protect sensitive electronic systems from voltage surges and spikes that can travel through their electrical power sources. They typically respond fast, reducing the voltage increase to a safe level within nanoseconds.The SMAJ90CA-13-F is one of these components, belonging to the SMF (stabilized manifolds) family and with peak pulse power ratings up to 600W. It is also characterized by its low leakage current, mainly varying from 0.01 up to 0.2 micro-amps.TVS diode’s primary function is that of limiting transient voltages, absorbing and redirecting high-energy pulses in the direction of low-energy, low-voltage environments. In order to achieve this, they must be placed across the power source and the system they are protecting, so that both are exposed during the transient.The SMAJ90CA-13-F is composed of two elements, between which an avalanche breakdown is mediated when exposed to a voltage that exceeds the breakdown voltage. This impulse is then focused away from the device so that it may be properly diverted into its designated ground path. This diode relies on a two-element configuration that forms a stabilizing sub-circuit, that dampens the pulse and helps reduce ringing into the protected circuit.Another key application of this diode is in overvoltage protector circuits. It works as a three-terminal device, with its auxiliary lead linked to the protected circuitry. This lead will short the positive or negative terminal of the diode, allowing for reliable transient suppression. This specific device is also able to handle a wide range of different polarity conditions, reaching a maximum clamping voltage of 25V for positive polarity, and 17.67V for its negative equivalent.All of these attributes make the SMAJ90CA-13-F a very reliable product, applicable in many industries. They include the automotive, telecommunications, IT, consumer electronics and many other sectors. It has been proven in both automotive and industrial lightning tests. Its low capacitance design also enables it to be used in the protection of data lines and other low-voltage circuits.Its low reverse leakage current property also contributes to its ESD protection. This measure is important for a satisfactory operation of electronic equipment, since sudden voltage spikes can be caused by nearby electrical discharges. The capacity of this diode to disperse the voltage quickly and without damage provides an efficient protection against turbulent weather conditions or otherwise damaging electromagnetic fields.In conclusion, the SMAJ90CA-13-F is a solid and versatile transient voltage suppressor diode with broad applications. Its fast response and high peak pulse power ratings make it a dependable choice for ESD protection and is also suitable for automotive and industrial lightning tests. It is a suitable option for lightning, overvoltage protector and low capacitance design.
