Additional Details:
The 1.5SMCJ200CA has a standoff voltage (Vrwm) of 200V, meaning it will not conduct under normal operating conditions below this voltage. The breakdown voltage (Vbr) is typically around 222V, and the clamping voltage (Vc) is approximately 324V at a peak pulse current (Ipp) of 4.6A. The peak pulse power is 1500W. The operating temperature range is typically -55°C to +150°C. The clamping factor (Vc/Vbr) is an important parameter that indicates the effectiveness of the TVS diode in limiting the voltage across the protected circuit. Proper PCB layout is crucial for optimal performance, minimizing inductance in the loop and ensuring a low impedance path to ground. The diode should be placed as close as possible to the input terminals of the protected circuit.
