1500W bidirectional TVS for 18V rails
It clamps both polarities from a single device, which saves board space on AC or bipolar signal lines compared to back-to-back unidirectional parts. Reverse standoff voltage is 18V, with a minimum breakdown of 20V and a maximum clamping voltage of 29.2V at the peak pulse current of 51.4A.
DO-214AB (SMC) package — field-swappable with hot air
It is large enough to hand-place with tweezers and reflow with a hot-air station — no lab bench required for a field swap. The package marking is legible under a loupe, so orientation (cathode band for unidirectional; bidirectional has no band) is clear. Surface-mount only — no through-hole option in this series.
