SMDA15-6TR Circuit Protection

SMDA15-6TR, a type of Transient Voltage Suppression (TVS) diode, is suitable for use in various electronic applications requiring overvoltage protection. It is designed to protect high speed devices from voltage surges caused by events such as electrostatic discharge (ESD), inductive switching, or lightning.

SMDA15-6TR is a unidirectional TVS diode, mainly used to absorb and dissipate voltages when the voltage difference across the device exceeds its peak pulse power rating. It can be used to protect system components such as microcontrollers, memories, analog-to-digital converters, optical modules, and other sensitive devices from damage caused by residual ESD and other transients. Additionally, it is designed to provide maximum EMI/RFI noise suppression, as well as surge and transient protection.

The TVS diode consists of a cathode and an anode. When a voltage is applied across the diode, current flows from the anode to the cathode through the semiconductor material. The current is limited by a high value resistor component inside the semiconductor material, which prevents the current from exceeding a certain value. The value of the resistor determines the peak surge current that the diode can safely handle.

The SMDA15-6TR has an ESD protectivity of 15kV (Contact Discharge), an operating temperature range of -55°C to 125°C, a typical peak reverse voltage of 6V, and a peak pulse power of 250W. It has an equivalent circuit consisting of two series Zener diodes and an ESD protection diode for superior performance.

SMDA15-6TR offers excellent overvoltage protection for a variety of applications, such as automotive, industrial, telecom, and consumer electronics. It can be used in applications such as vehicle audio systems, computer peripherals, handheld electronic devices, and remote sensors. Additionally, it is widely used to protect electrical components and systems from surge currents or transients caused by lightning strikes.

In summary, the SMDA15-6TR is a reliable and robust TVS diode that provides protection against overvoltages caused by ESD, inductive switching, and other transients. It offers a wide operating temperature range and an ESD protectivity level of 15kV. Additionally, it can be used to protect a variety of electrical components and systems in automotive, industrial, telecom, and consumer electronics.
