TVS (Transient Voltage Suppressors) diodes are reliable and cost effective components to protect electronic devices and circuits from electrical overstress. One such component is SMDA03C/TR7, that offers breakthrough components in the protection of sensitive electronics from voltage transients. The SMDA03C/TR7 provides protection from the lowest to the highest capacitances in the voltage range from 55V to 1500V, and does so with the highest thermal stability.

The SMDA03C/TR7 are configured as an array of silicon avalanche diode structures for use in ultra-low capacitance applications. The diode has a high-speed avalanche behavior that has been tailored to maximize protection against transients from 36V up to 1500V. This protects devices from the damaging immune effects of voltage transients and thus provides the reliability and long-term integrity of the protected electronic device or circuit.

The SMDA03C/TR7 self-activated diode is constructed by connecting many avalanche diodes in parallel and is housed in an SMA, virtually indestructible, package. It uses the avalanche effect to clamp high-energy transient voltages to a safe level and thereby protect the electronic device from damage or destruction. The avalanche capacitance on the SMDA03C/TR7 is much lower than many other available TVS diodes, making it suitable for protecting ultra-low capacitance applications. Each diode has been tested to withstand repetitive transients of up to 1500V.

The working principle of the SMDA03C/TR7 diode is simple. When a voltage transient occurs, the silicon avalanche diode structures turn on, clamping the overvoltage to a safe voltage level. This protects sensitive electronic devices from overvoltage damage. After the transient has passed, the avalanche diodes turn off and the voltage returns to its normal level. This process is repeated whenever a transient occurs, and the diode is capable of handling repetitive transients without any damage.

The SMDA03C/TR7 application field is mainly used in automotive, industrial and consumer electronics. It is ideal to provide protection against lightning transients, electrostatic discharge (ESD), and EMI/RFI noise from the power line. The SMDA03C/TR7 diode also finds its place in portable electronic equipment, such as mobile phones and handheld devices that must be protected from damaging transients.

The SMDA03C/TR7 offering offers outstanding performance at an economical price and is available in an array of package styles to suit any application. It is available in various current ratings from 1.2A to 5A, with a wide range of operating temperatures. The diode is also RoHS compliant, lead free, and halogen free, making it an environmentally-friendly alternative to traditional overvoltage protection components.

In conclusion, the SMDA03C/TR7 is a powerful and reliable TVS diode which offers an incredibly efficient protection system against transient voltages. It is suitable for use in a wide range of applications, is extremely cost-effective compared to other available solutions, and is available in many package styles. Its low-capacitance design enables an efficient and reliable protection system for ultra-low capacitance applications.
