Its reverse standoff of 40 V sets the working rail it protects — the device sits idle below that and clamps above it. Breakdown minimum is 44.4 V; under a 10/1000 µs surge the clamping ceiling is 64.5 V at a peak pulse current of 23.3 A. The 1.5 kW peak pulse rating defines the surge energy the SMC package can absorb one-time without degradation — the clamping voltage at 23.3 A is what the downstream circuit actually sees during the event. ## DO-214AB SMC foot print, surface mount The strip packaging indicates reel-taped units for automated pick-and-place; confirm the reel quantity matches your line feeder capacity before the first build.","metaTitle":"Diotec 1.5SMCJ40CA-AQ TVS Diode, 40V standoff, 1.5kW","metaDescription":"Diotec 1.5SMCJ40CA-AQ bidirectional TVS Zener, 40V standoff, 44.4V breakdown, 64.5V clamping at 23.3A peak pulse, DO-214AB SMC.
