1500W peak pulse — what the clamping spec means
The 1.5SMC56CA TR13 PBFREE: For a board-level protection zone, the 77 V clamping ceiling is what the downstream circuitry must survive; the 53.2 V minimum breakdown voltage is the point above which conduction begins, so the standoff of 47.8 V sets the normal operating headroom before the device even begins to conduct. Bidirectional — the single channel clamps both polarities, which is the configuration required for AC rails or floating DC references. Operating junction temperature runs to 150 °C, so the -65 °C lower limit covers cold-start and outdoor-equipment environments; the upper bound means the clamping performance is characterised through the full industrial temperature band. Power Line Protection is listed as No — this device is suited for board-level signal and component protection, not for inline mains rail clipping, which is consistent with the DO-214AB SMC package not carrying a safety-agency rating as a standalone protective device.
DO-214AB SMC — surface mount and tape-and-reel fit
The DO-214AB (SMC) package is the mid-size SMA/DO-214AC footprint — the cathode band on the sleeve identifies polarity on the bidirectional variant. Surface-mount termination suits reflow assembly; the tape-and-reel quantity ties the standard reel count to the production run. General-purpose application rating means no extra screening or burn-in is applied beyond the base part — no AEC qualification, no JAN screening. Available as standard commercial grade from Central Semiconductor Corp.
