Minimum breakdown voltage is 83.3V, which sits 11% above the 75V standoff. That margin prevents the diode from conducting during normal rail ripple or steady-state overvoltage, while still triggering early enough to limit stress on the load. The 11.2A peak pulse current at the 10/1000µs waveform is the current the diode shunts to ground during the clamp event — the 1500W product of clamp voltage and current confirms the power handling.
The base part number SMCJ75E3 refers to the TVS diode itself, while the /TR13 suffix indicates the Tape & Reel packaging format. The electrical characteristics — 1500W peak pulse power, 75V standoff, 134V clamp — are identical. The /TR13 variant is the reeled version for automated SMT assembly.
