This is the standard TVS rating condition per IEC 61000-4-5; the actual energy-handling capability for shorter transients (e.g., 8/20µs) is significantly higher. The 36A peak pulse current at the 43.5V clamp level confirms the device can absorb substantial surge energy without exceeding its junction temperature limit. The bidirectional configuration (single channel, symmetrical breakdown at 27V min) means the TVS clamps both positive and negative transients with equal performance. This is essential for AC-coupled signal lines or power rails that may see reverse polarity events, as it eliminates the need for a series diode. ## Active production — qualified for automotive BOMs For new designs, the part number 1.5SMC30CH is the current production order code.","metaTitle":"1.5SMC30CH TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC30CH: 1500W bidirectional TVS, 24.3V standoff, 43.5V clamp, AEC-Q101 automotive grade.
