ESD9R3.3ST5G Datasheet/PDFPacked with the ever advancing technological world, the television semiconductor, especially the diodes is not left behind. This type of semiconductor is one of the important components of electronics and it typically consists of N-type and P-type regions connected together. It is used to cathodic protection in environments such as lightning and electrostatic discharge.
ESD9R3.3ST5G is a diode type in order to safeguard electronics, controlling the flow of electricity with its two-directional attributes. It forms part of the television semiconductor that is based on the PN-junction technology.
Primarily, the ESD9R3.3ST5G is designed to protect sensitive electronics from low power electrical and electro-magnetic disturbances such as static electricity and transients. It is a very small and low capacitance device, designed to withstand surge voltages of extremely high levels. It is employed in slow switching circuits such as TV receivers and transceivers, as it allows smooth transition from active to standby mode. It is also used in mobile devices and laptop computers. Additionally, it is also suitable for high speed data line protection.
The ESD9R3.3ST5G is a bidirectional transient voltage suppressor diode. When the forward bias exceeds the rated peak inverse voltage (PIV), the PN junction breaks down and the device acts as a voltage clamp, limiting the voltage of the electronic device to a minimum. When the transient is over, the device returns to its high impedance state, without any residual current.
In the reverse bias, the device has a breakdown voltage characteristic or “cliff” that eliminates the “knee” or gradual decrease in voltage that is characteristic of a Zener diode. This gives excellent low capacitance protection for all types of digital signals.
Therefore, the device’s operation, starting from a rectifier diode, an ESD protected switch, a voltage regulator, a voltage dependent resistor, a surge suppressor, and an ESD protected clamp makes it an ideal choice for mains or battery powered applications.
