TVS (Transient Voltage Suppressor) diode is a kind of semiconductor device which can limit and protect the circuit overvoltage transient. SMAJ90CAHE3/5A is a kind of fifth generation of overvoltage suppressor diode developed by SMC company. It has a unidirectional voltage and is composed of two semiconductor elements.

The working principle of SMAJ90CAHE3/5A is that the two semiconductor elements can be turned on under the effect of overvoltage. During the working process of the element, when the voltage exceeds the breakdown voltage, the electrode current will be anchored. The current passes through the PN junction of the element and flows into a known path.

In addition to having the characteristics of breaking down quickly and self-recovery after breakdown, the thyristor diode can also be delivered in a wide range of lightning protection voltages of 30V～330V, and meanwhile can reduce the volume of manufactured products. It provides TVS solution for the production of mobile consumer electronic products which is smaller than 15mm.

SMAJ90CAHE3/5A is widely used in the field of consumer electronics, such as mobile phones, mainly for protecting circuit components from overvoltage. With the rapid development of mobile phone industry, the functions of mobile phones are becoming more and more powerful. Therefore, the requirement of overvoltage voltage protection circuit of mobile phone is getting higher and higher. The lightning protection voltage provided by SMAJ90CAHE3/5A is up to about 330V, which can fully meet the lightning protection requirements of mobile phones.

In addition, the SMAJ90CAHE3/5A can also be applied to other fields. It can be used in AC to AC communication line for lightning protection. Moreover, it can also be used in the industrial site and residential electronic circuit protection.

In conclusion, SMAJ90CAHE3/5A is a TVS diode which can be used for a wide range of applications, including mobile phones, AC to AC communication lines, industrial and home electronic circuits. Its working principle is based on two semiconductor elements which can quickly break down when the voltage exceeds the breakdown voltage. The lightning protection voltage provided by this device is up to about 330V, which makes it an ideal device for the protection of circuits from overvoltage.
