What the 500W rating means for your protection budget
For a 7.6V reverse standoff voltage, the clamping voltage hits 14.5V at the rated 34.5A peak pulse current, so the downstream circuitry needs to survive that clamp ceiling.
Bidirectional — one part for symmetrical rails
The breakdown voltage starts at 9.5V minimum, so the part stays out of conduction below that threshold.
The axial leaded package (B, Axial case) is a through-hole form factor that stores well on tape or in bulk tubes; no moisture sensitivity level to track.
Through-hole mounting (axial leads) suits point-to-point wiring, terminal blocks, or PCB through-holes — the lead bend radius matters for stress relief in high-vibration environments.
