The STMicroelectronics SM15T220CA is a 1500 W bidirectional TRANSIL™ TVS diode in an SMC package, designed to clamp transients on general-purpose power and signal lines.
STMicroelectronics lists the SM15T220CA as an active product.
No power line protection feature is claimed — this is a general-purpose transient suppressor, not a dedicated rail-clamp array.
The SM15T220CA is rated for 1500 W peak pulse power (1.5 kW) per the 10/1000 µs waveform, with a peak pulse current of 26 A for the 8/20 µs waveform.
Yes, the SM15T220CA is a single bidirectional channel device, clamping both positive and negative transients.
