Breakdown starts at 31.4 V minimum, giving a 3.2 V guard band before the TVS begins conducting. Maximum clamping voltage of 45.7 V at 34 A peak pulse current sets the voltage the protected IC sees — a downstream 60 V-rated DC-DC converter or 50 V-rated capacitor has enough headroom to survive the clamp. Single bidirectional channel means one device protects a signal pair (e.g., CAN bus lines or a differential data pair) without needing two unidirectional diodes back-to-back — saves board space and reduces part count. ## DO-214AB package and thermal handling Operating junction temperature range of -55°C to 150°C covers the full automotive ambient envelope, including cold-crank at -40°C and under-hood soak at 125°C, with margin for self-heating during repetitive surges. Supplied in Tape & Reel packaging for automated pick-and-place assembly — no manual handling required, which keeps the assembly line ESD-safe and consistent.","metaTitle":"1.5SMC33CAH TVS, 1500W, 28.2V, DO-214AB","metaDescription":"1.5SMC33CAH bidirectional TVS diode, 1500W peak pulse, 28.2V standoff, AEC-Q101 automotive grade.
