TVS - Diodes

TVS – Diodes, often referred to as Transient Voltage Suppressors, are a family of diodes specifically designed to protect equipment from high voltage transients. TVS Diodes are an ideal solution for providing surge protection. TVS’s provide excellent clamping protection at power and data lines from a variety of environmental conditions including Electro-magnetic Interference (EMI), Electro-static Discharge (ESD), lightning, and other various transient events.

The SMAJ11CATR is a Thyristor Surge Protective Device (TSPD) designed to provide transient protection for data, power and signal lines. It is constructed using a Transient Voltage Suppressing diode with an integrated protection circuit, allowing it to detect overvoltage transients and provide an instantaneous output turn-off. The device is suitable for applications where transient voltages in the range of 3.3V to 350V are encountered. It is designed to provide good transient protection, offering an operating capacitance of 3 pF max and a typical Leakage Current of 4 uA at 5V.

The working principle of the SMAJ11CATR is simple. When a transient exceeds the breakdown voltage (VBR) of the Zener diode, the protection circuit interrupts the current flow from the power line. The SMAJ11CATR also features a Response Time of 35nsec, allowing it to respond quickly and protect against transient overvoltages. This is especially useful in applications like cell phone chargers, where a fast response time is necessary to protect the phone from damaging transients.

The SMAJ11CATR is an ideal product for data, power, and signal line protection applications. It offers excellent voltage clamping at 3.3V to 350V and low capacitance, as well as a response time of 35nsec. It can be used in a variety of applications such as cell phone chargers, computers, communication units, and many other devices that make use of high speed and/or high voltage circuit designs.

The SMAJ11CATR is a reliable and cost-effective solution for protecting data, power, and signal lines from transient voltage spikes. Its low capacitance and fast response time make it an ideal choice for a wide range of applications. It is capable of providing excellent voltage clamping and offers a response time of 35nsec to protect against transient overvoltages. With its wide application field and simple working principle, the SMAJ11CATR is a cost-effective and reliable solution for multiple line protection.
