The 1.5SMC200AH: Its 171 V reverse standoff voltage protects 170 V nominal rails, clamping transients to 274 V maximum at 5.7 A peak pulse current. The -55°C to 150°C junction temperature range covers the full automotive thermal profile.
The unidirectional channel means it clamps positive transients above breakdown; for bidirectional protection on AC or bipolar rails, a series pair or a bidirectional variant is needed.
Yes, it is AEC-Q101 qualified, meaning it meets the automotive-grade reliability and temperature requirements for use in engine bay, chassis, and body electronics. The operating junction temperature range is -55°C to 150°C.
