P1101SC is an advanced protection product for various analog and digital circuits, embedded systems and new energy vehicles, researches in universities and academies, aerospace industry, medical treatment, high power equipment and home appliances, etc. This device is classified into the TVS - Mixed Technology Serials.

This P1101SC device features a very wide spectrum range, 150V to 387V. Moreover, it offers advanced features such as stand-off voltage up to 2000V for high power usage. It includes low capacitance for fast signal transmission and low leakage current to provide very good and consistent protection performance. The P1101SC device is lead-free and is capable of withstanding up to 7kV for 8/50us pulse without resetting. It has a very reliable surge current capability of 20A at 200V and 40A/ms.

The working principle of the P1101SC device is simple. When the signals in the device reach the high threshold voltage of the device, the internal surge protection circuits start to protect the device from the potential of overvoltage and over-temperature. In addition, several on-board circuits are activated to protect against voltage surges, reset the device and restore the input voltage to a normal operating value.

The device itself has several components to make its working efficiency. The major components of the P1101SC device are Polysilicon Gate (PG), insulated gate P-channel MOSFET (IGP), PN junction protection field effect transistors (PFETs), and diode array. PG is used to protect the device from voltage surges, while IGP is responsible for providing fast intra-packet signal transmission. The diode array helps to protect against lightening and high transient voltages, while PFETs provide reset control.

Moreover, the P1101SC device\'s optimal damping oscillation features are available in two optional modes: Active Pulse Width Modulation (APWM) and Current Limited Dynamic Activation (CLDA). These two modes help to reduce inrush current and eliminate the risk of device resetting due to high transient noise. In APWM mode, the device\'s inner transistors open up gradually and the current gradually builds up avoiding sudden current pressure while in CLDA mode, the device\'s transistors open up fast and keeps the current within the device parameter.

P1101SC devices, classified as TVS - Mixed Technology, are widely used in a variety of applications in the industry related to high power products such as telecommunication, industrial automation, automotive electronics and new energy vehicles. This series of devices is highly reliable and offers superior performance in protecting against different voltage surges present in a wide variety of applications.
