Once the transient exceeds 86.7 V minimum breakdown, the device avalanches and clamps the voltage to 126 V maximum at 11.9 A peak pulse (10/1000 µs waveform), shunting the surge current away from downstream circuitry — the 126 V ceiling is what the downstream IC or MOSFET gate sees. ## Automotive temperature grade A module mounted near the alternator or DC-DC converter that runs at 125°C ambient still has thermal headroom before the junction ceiling is hit. The automotive application flag means Diotec qualifies this part for the typical automotive screening and traceability stack — confirm lot traceability and any AEC-Q101 alignment requirements with your Diotec sales contact before committing to a new design. ## SMC/DO-214AB footprint Surface-mount SMC (DO-214AB) package with a thermal pad under the body — the cathode bar is the larger pad; PCB layout should keep the pad solder-wetted to the landing pattern to maintain the rated thermal resistance to the board. Strip packaging is the standard reel-free format for prototype reels and manual-assembly runs; confirm the full reel quantity requirement for production quant.","metaTitle":"Diotec 1.5SMCJ78CA-AQ TVS, 126V Clamping, SMC","metaDescription":"Bidirectional 1.5kW TVS diode, 78V standoff / 126V clamping, 11.9A peak pulse, -50°C to 150°C TJ automotive temp grade.
