Additional Details:

The P6SMB6.8A-E3/5B is a TVS diode available in an SMB (DO-214AA) package for surface mount assembly. It has a standoff voltage (working voltage) of 6.8V, meaning it doesn't conduct until the voltage exceeds this level. The breakdown voltage typically ranges from 7.22V to 8.0V. The clamping voltage is specified to limit the voltage across the protected component during a surge event. The device can handle a peak pulse power of 600W. The “E3” designation indicates lead-free construction, and “/5B” likely refers to a specific packaging or testing standard. The operating temperature range typically spans from -55°C to +150°C. This component is suitable for automated assembly processes.
