NCP360SNAFT1G Application Field and Working Principle

The NCP360SNAFT1G Transient Voltage Suppressor is a mixed technology TVS from Nexperia, available in a small and cost-effective SOT-23 package. The device is designed to protect sensitive equipment against voltage spikes. It employs a combination of Zener diodes and transistors to protect against overvoltage and ESD transients. This device is most commonly used in communication devices, computers, and consumer electronics.

Features

The NCP360SNAFT1G features a robust 380 Watt peak power capacity with a low operating temperature range of -65°C to +150°C and a maximum bidirectional operating voltage range of 5.5-14 V. It also offers a fast response time of less than 1 nanosecond (ns), a minimum capacitance of 10 pF, and a low-clamping voltage of 32-36 V.

Applications

The NCP360SNAFT1G is ideal for applications that require robust ESD protection from overvoltage. It is commonly used in equipment for communication, computer, and consumer electronics, such as home appliances, smart phones, computer peripherals, medical devices, and automotive components.

Working Principle

The NCP360SNAFT1G uses a combination of transistors and Zener diodes to provide overvoltage protection. During normal operation, the devices are in a low-impedance (high-conductance) state and allow current to flow freely. When an overvoltage event occurs, the transistor switches into a high-impedance (low-conductance) state, diverting current away from the protected circuit and allowing the Zener diode to clamp the voltage at a safe level. The clamped voltage is limited by the Zener voltage breakdown value, which is between 32-36V.When an ESD voltage surge occurs, the Zener diode reacts by limiting the voltage to a safe level. The transistor provides the necessary high-impedance state, which helps to keep the components in the protected circuit from facing an uncontrolled and damaging voltage spike.

Conclusion

The NCP360SNAFT1G Transient Voltage Suppressor is a mixed technology TVS with a robust 380 watt peak power capacity, a low operating temperature range of -65°C to +150°C, and a maximum bidirectional operating voltage range of 5.5-14 V. It is designed for use in applications requiring robust ESD protection from overvoltage, such as home appliances, smart phones, computer peripherals, medical devices, and automotive components. The device is composed of a combination of transistors and Zener diodes, and works by providing a low-impedance state during normal operation, while in the event of an overvoltage or ESD occurrence it switches into a high-impedance state and uses the Zener diode to safely limit the voltage.
