TVS (Transient Voltage Suppressors) diodes are used to protect AC and DC circuits from coming in contact with transient overvoltage conditions. The SMAJ530HE3_A/H TVS Diode, which belongs to the AVR series of TVS diodes manufactured by ITT Interconnect Solutions, is an ideal low voltage ESD (Electrostatic Discharge) protector for data lines such as RS-232, RS-422, RS-485, V.35, and 10/100Base-T Ethernet. Due to its low voltage rating and high surge current rating, this device is well-suited for portable electronic devices.

Features

The SMAJ530HE3_A/H TVS Diode has a working voltage of 5.6V, making it ideal for use with low voltage circuits. It comes with an Ipp (maximum peak pulse current) of 5.3A (8/20μs, 10/1000μs) and a Clamping Voltage of 9.2V (8/20μs, 10/1000μs) at Ipp. Additionally, it has a rated dissipation power of 500 W (at TA =+25°C) and an excellent peak pulse power dissipation of 4.4 KW (10/1000μs). Finally, this device has a low leakage current of 1.0 μA (at VM =5.6V).

Applications

Due to its low voltage rating and high surge current rating, the SMAJ530HE3_A/H TVS Diode is well-suited for protecting signaling, data, and power lines in all types of portable electronic equipment such as laptops, tablets, cell phones, PDAs, and other electronic devices. It is especially useful in applications such as RS-232, RS-422, RS-485, V.35, and 10/100Base-T Ethernet, where its low voltage rating and excellent surge performance guarantee complete protection from transient voltage spikes.

Working Principle

When a surge voltage is applied to the SMAJ530HE3_A/H TVS Diode, the PN junction is forced to become forward-biased, causing current to flow and thus effectively clamping the voltage across it. As soon as this surge current is cut off, the TVS diode will reset itself to its non-conducting state. In this way, it is able to protect downstream circuitry from the potentially damaging effects of transient overvoltage.

The SMAJ530HE3_A/H TVS Diode is a robust device with excellent surge current performance, making it ideal for protecting portable electronic devices from transient overvoltage. With its low working voltage rating and high surge current rating, this device offers reliable ESD protection for all types of portable equipment.
