Its reverse standoff voltage is 8V, and the breakdown voltage starts at 8.89V — the point where the device begins conducting to shunt excess energy away from the protected circuit. Rated for 500W peak pulse power under the 10/1000µs waveform, it handles a peak pulse current of 33.3A before the clamping voltage reaches 15V. That 15V ceiling is what the downstream silicon sees — keep it below the absolute maximum of any IC on that rail.

Yes, it has a single bidirectional channel, clamping both positive and negative transients symmetrically.
The SMAJ8.0A is a unidirectional TVS, while the SMAJ8.0CE3/TR13 is bidirectional — the key difference is polarity handling. Both share the same DO-214AC package and similar voltage ratings, but the 'C' in the part number indicates bidirectional construction.
