600W peak pulse, 12V rail — one bidirectional device
Breakdown occurs at a minimum of 13.3V, and the clamping voltage is held to 19.9V max at the rated peak pulse current of 30.2A. That 6.6V window between standoff and clamp gives the downstream circuitry a decent safety margin before the TVS fully conducts — useful when the protected rail has a 12V nominal tolerance band.
Active production, surface-mount package
The DO-214AA (SMB) package is a common footprint; the tape-and-reel delivery (TR13 suffix) suits automated pick-and-place assembly.
Temperature range and general-purpose fit
The general-purpose application classification means no power-line protection features — this is a signal- or low-power-rail clamp, not a mains surge suppressor.
