The 1.5SMC200CA-E3/9AT: The 171 V reverse standoff voltage means it sits across a 170 V DC bus without conducting leakage; when a transient exceeds the 190 V minimum breakdown, the device clamps to 274 V at the rated 5.5 A peak pulse current (10/1000 µs waveform).
The -65°C to 150°C junction temperature range covers industrial and telecom enclosures where ambient heat plus self-heating from repetitive surges pushes the die above 125°C.
