TVS-Diodes are a special type of diode that helps protect electronic components by limiting transient voltages created by a nearby EMI source. It acts as a back-to-back pair of Zener diodes with a wide variety of features to protect against electrical transients and EMI sources. One such diode is the SMAJ30C-E3/61.

An SMAJ30C-E3/61 diode is made with a bidirectional ultra-low capacitance diode array which has two Zener diodes connected in series and is designed to protect sensitive components such as data lines from high-speed ESD and EFT. It can also be used to provide protection against lightning and electrical transients. It has a low capacitance value of 0.2pF and a working voltage of 30V. Its fast response time and minimized footprint design makes it very suitable for a wide range of applications.

The SMAJ30C-E3/61 diode is mainly used in consumer devices, computers, telecom, and automotive applications. For example, it can be used to protect data and power lines from EMI sources in mobile phones and tablets. It is also ideal for protecting computers, modems, and other sensitive components in a network infrastructure. This low capacitance diode is also suitable for automotive applications, as it is designed to reduce the impact of electrical transients caused by lightning strikes.

The SMAJ30C-E3/61 diode works by connecting two Zener diodes in series. When a high voltage pulse is detected on either the anode side or the cathode side of the diode, the Zener diodes will conduct a current which shunts the voltage and dissipates the energy. This reduces or eliminates the damage caused by the voltage surge. The low capacitance value of the diode enables it to respond quickly and accurately to transients, thus providing reliable protection from voltage spikes.

Other features of this diode include a wide operating temperature range between -55°C to +150°C, a high electro-thermal stability, and high peak pulse power capability up to 9500W at 10/1000μs waveforms. It also meets the requirements of the UL1449/CSA 22.2/ IEC 61000-4-5 standard.

The SMAJ30C-E3/61 diode is an ideal solution for protecting sensitive electronics from voltage spikes, EMI sources, ESD pulses, and lightning strikes. Its small size and wide operating temperature range make it ideal for a variety of applications, such as consumer devices, computers, and automotive power systems. Its low capacitance values allow it to respond quickly and accurately to transients, providing reliable protection from voltage surges.
