Additional Details

The P2304 features a specific standoff voltage, which is 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 P2304 is typically used with a series resistor to limit the current flowing through the SIDACtor during a surge event. Proper grounding techniques are essential for effective surge protection. Consult 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. The axial lead package allows for easy soldering and mounting on PCBs. Littelfuse offers a variety of SIDACtor devices with different voltage and current ratings to meet the specific requirements of various applications.
