Its 50V minimum breakdown voltage means it starts conducting just above the working voltage, and the 72.7V maximum clamp at 8.3A peak pulse current limits the voltage spike the downstream circuitry sees.
With a single bidirectional channel, this diode clamps both positive and negative surges — no need to orient the part on the board for polarity.
Yes, it has a single bidirectional channel — it clamps surges of either polarity on the same line.
