The 8 V window between standoff and clamp gives the downstream regulator or IC a defined overvoltage ceiling — a tighter window than some generic 1.5 kW TVS parts, which matters when the protected device has a 30 V absolute maximum rating. ## Package and temperature range — board-fit notes The DO-214AB (SMC) package is a standard JEDEC outline with a copper tab on the cathode side — the PCB land pattern should follow the manufacturer's recommended pad geometry to keep the thermal impedance low during a surge event. The 1.5 kW rating is derated above 25°C per the datasheet curve; at 125°C junction, the peak pulse power typically drops to about 75% of the 25°C value.","metaTitle":"SMCJ14CAE3/TR13 TVS Diode – 1500W Bidirectional, DO-214AB","metaDescription":"SMCJ14CAE3/TR13 Zener TVS diode, 14V standoff, 23.2V clamp, 64.7A peak pulse, 1500W.

The breakdown and clamp voltages are identical — 15.6 V min breakdown, 23.2 V max clamp — but the unidirectional SMCJ14A only protects one polarity. If your circuit needs protection on both a positive and negative rail relative to ground, the bidirectional SMCJ14CAE3/TR13 replaces two unidirectional parts.
