Product details

1500 W bidirectional clamp — the numbers that decide the fit

The 1.5SMC220CA-M3/57T: With a 185 V reverse standoff voltage and a 328 V maximum clamp at 4.6 A peak pulse current, this part protects 185 V nominal rails — common in three-phase rectified DC buses or 120/240 VAC telecom rectifier outputs — by clamping transients before they reach downstream silicon. The 209 V minimum breakdown voltage gives the designer a 24 V window between the rail and the avalanche threshold, enough to ride through normal line ripple without nuisance clamping.

Tape and reel packaging (TR suffix) aligns with high-volume pick-and-place — the reel quantity matches the standard 7-inch or 13-inch reel formats for DO-214AB.

Frequently asked questions

What does the 1500 W peak pulse power rating mean for my circuit?

The 1500 W rating is measured with a 10/1000 µs exponential waveform — the standard telecom surge. For shorter pulses (8/20 µs) the peak power capability is higher; for longer transients it derates. The 328 V clamp at 4.6 A tells you the TVS holds the line voltage below the downstream device's abs-max rating during the surge event.
