1500 W peak pulse in a DO-214AB footprint
The 1.5SMC160A: It clamps transients on a 136 V nominal rail, with a breakdown voltage range starting at 152 V and a maximum clamp voltage of 219 V at the 6.9 A peak pulse current. The DO-214AB (SMC) package suits reflow assembly on standard power-supply or I/O protection footprints.
Clamp voltage and rail protection margin
With a 136 V reverse standoff voltage, this part protects 120 VAC or 130 VDC rails where the normal operating peak stays below the standoff. The 152 V minimum breakdown ensures the TVS does not conduct during nominal line or bus ripple. The 219 V clamp at 6.9 A sets the voltage the downstream equipment must survive — a 20% margin above the rail's transient peak is typical for a robust design. The 1500 W peak pulse rating at 10/1000 µs is the standard industrial surge waveform. For shorter transients (8/20 µs), the part handles higher peak current; for longer events, derate per the pulse derating curve.
