That clamp ceiling is what the downstream silicon sees — if the protected IC's absolute max rating is, say, 50V, this part leaves only 1.6V of headroom, which is tight. The 1500W rating is the energy it can absorb in a single 10/1000µs pulse; for shorter transients (like ESD), the effective power capability is higher. The wide range means derating the peak pulse power at elevated temperatures — the datasheet's derating curve is the reference for that calculation.","metaTitle":"SMCJ30CAE3/TR13 TVS Diode - 30V Bidirectional, 1500W","metaDescription":"SMCJ30CAE3/TR13 Zener TVS diode, 30V reverse standoff, 48.4V clamp, 1500W peak pulse, DO-214AB.

The 30V reverse standoff voltage sits above the 24V nominal bus, so the TVS does not conduct during normal operation. It triggers when the transient exceeds the 33.3V minimum breakdown voltage."},{"question":"What is the closest pin-compatible alternative to SMCJ30CAE3/TR13?","answer":"The base product number SMCJ30 covers the same die in the same DO-214AB package.
