TVS (Transient Voltage Suppressors) Diodes are a type of electronic component specifically designed to protect electronic devices from damage due to transient voltage surges, sharp rise of voltage not exceeding given peak and clamping voltage levels, such as those produced by lightning. They are the main form of electrical protection for electronic components and systems, primarily for AC line voltage supplies.

The SA16A-E3/73 is an ultra low capacitance, ultra low clamping voltage and ultra low capacitance TVS diode that provides ESD protection for data lines and port interfaces. This TVS diode is designed to protect against electrostatic discharge (ESD) for a wide variety of applications, including automotive, telecommunications, consumer electronics, and computers. It is a three-pin surface mount device with a voltage rating of 70V and a maximum operating temperature of 105°C.

The SA16A-E3/73 is a bi-directional TVS diode that can protect two different lines in the same direction. Its ultra-low capacitance design (Cpf = 4pF typical) keeps signal speed and performance nearly unchanged while providing reliable ESD protection in systems up to 2000V human body mode (HBM). It also offers excellent surge handling capabilities in operations like telecommunication applications (IEC 61000-4-5 8/20s).

In order to protect vulnerable transistor circuits from high voltage and current produced by ESD, the operating principle of the SA16A-E3/73 TVS diode consists of internal P-N junctions that switch from a high impedance state to a low impedance state when a predetermined current threshold is exceeded. When applied to a given line, the SA16A-E3/73 can quickly detect and clamp the transient voltage to protect the device and circuitry upstream of the diode. This helps to ensure that the line is not damaged and that the system is able to re-establish normal operation.

The SA16A-E3/73 is mainly used to protect mobile phones, digital cameras, automotive parts, and various computer interfaces such as USB and Firewire. By providing reliable ESD protection, it helps to prevent damage due to ESD surges and voltage transients caused by lightning, static electricity, and electrostatic breakdown. Its ultra-low capacitance, ultra-low clamping voltage, and ultra-low junction capacitance ratings make it ideal for applications where signal speed and performance must remain unchanged.

The SA16A-E3/73 TVS diode is a popular choice for data line and port interface protection. Its reliable protection and low capacitance make it suitable for a wide range of applications. Its small surface mount package and excellent AC characteristics make it easy and cost effective to implement in the design of various electronic devices.
