The SD15C-01FTG is a TVS – diode that is used as an overvoltage protection solution in various applications. It is a bidirectional diode that can effectively protect circuits against overvoltage transients and ESD. The device is designed in a small plastic SMC (SOD-323 package), offering superior performance and superior protection in a wide variety of applications.

The SD15C-01FTG provides excellent protection against lightning induced transients, electrostatic discharges, and other electrical disturbances that can adversely affect the performance of electronic components and systems. The device is designed to be ESD compliant to the IEC 61000-4-2 standard. Additionally, it can handle up to 15A of peak pulse current, along with maximum voltage rating of 12V. The diode also features a low leakage current of typically 0.1 µA at up to 8V supply voltage.

The key advantages of the SD15C-01FTG TVS diode are its extended surge capability, low capacitive coupling, and low operating voltage. These features enable the device to protect a wide variety of applications, such as computer peripherals and communication equipment. Additionally, its small size and low leakage current make it ideal for use in portable devices and battery-powered systems.

The working principle of the device involves a reverse voltage blocking path that is triggered by an increase in the supply voltage. When the voltage exceeds the maximum rating of the device, the reverse voltage blocking path opens, allowing the current to pass through the diode. At this point, the diode begins to act like a resistor, limiting the current and protecting the device from possible damage.

The SD15C-01FTG is capable of withstanding transient voltages up to 1500V and is rated for up to 15A of peak pulse current. Its low capacitive coupling and low operating voltage enable it to provide superior protection for electronic systems in applications such as power supplies, process control, medical equipment, and automotive electronics. It is also suitable for use in consumer products, automotive assemblies, and military applications.

The SD15C-01FTG is designed to meet requirements of various safety and EMC standards, including UL 1960, EN 60950, IEC 60950 and EN 61000-4. The device is also RoHS compliant. It offers protection for a wide range of overvoltage events, such as electrostatic discharge, sky radiation, and overvoltage transients. The device is also designed to be highly reliable with low failure rates.
