Additional Details:

The TPSMB6.8HE3 has a standoff voltage of 6.8V. The peak pulse power dissipation is a critical parameter and should be considered when selecting a TVS diode. The clamping voltage is the voltage across the TVS diode when it is conducting. The operating temperature range is also an important factor to consider. Refer to the datasheet for detailed specifications on surge waveform, clamping voltage, and reverse leakage current.
