Additional Details

The P2300SCMCLRP features a standoff voltage of 230V, indicating the maximum voltage that can be applied continuously without triggering the device. The clamping voltage is the voltage to which the transient is limited when the device is conducting. Key electrical characteristics include its peak pulse current (Ipp), holding current (Ih), and breakover voltage (Vbo). The device is typically used in conjunction with a series resistor to limit the current flowing through the SIDACtor during a surge event. Proper grounding techniques are crucial for effective surge protection. Refer to the manufacturer's datasheet for detailed specifications, application notes, and recommended circuit configurations. The operating temperature range should also be considered for optimal performance and reliability. Littelfuse offers a variety of SIDACtor devices with different voltage and current ratings to meet the specific requirements of various applications. The SCMCLRP indicates a specific package and termination style which can be found in the Littelfuse documentation.
