Additional Details:

The P4SMAJ200CA has a standoff voltage (reverse working voltage) of approximately 171V, meaning it will not conduct under normal operating conditions below this voltage. Its breakdown voltage is typically around 222V, and its clamping voltage at a specific peak pulse current is usually in the range of 300V. The peak pulse power dissipation is 400W. It's packaged in an SMA (DO-214AC) package. The operating temperature range is typically -55°C to +150°C. The specific clamping voltage, surge current capability, and other electrical characteristics can be found in the manufacturer's datasheet.

This TVS diode is a cost-effective and reliable solution for protecting electronic circuits from a wide range of voltage transients. Its bidirectional capability, high surge capability, and low clamping voltage make it a versatile component for enhancing the robustness of electronic products.
