1500 W bidirectional Zener — 8.65 V breakdown floor
Its minimum breakdown voltage of 8.65 V sets the clamp threshold for a 7.5 V reverse standoff rail — the part stays transparent below that DC level and only conducts when a transient pushes past the breakdown knee. The clamping voltage is held to 13.4 V maximum at the rated 112 A peak pulse current.
DO-13 through-hole — temperature range to 175°C
The through-hole body suits point-to-point wiring or socketed boards where rework access matters.
Both share identical electrical characteristics — the /TR variant is simply the reeled option for volume pick-and-place.
