Automotive-grade TVS for 28V rails
The 1.5SMC33CAHR7G: It clamps at 45.7V maximum with a 28.2V reverse standoff, making it a fit for protecting 24V automotive power buses from load-dump and inductive kickback transients. AEC-Q101 qualification means this part has passed the automotive reliability stress tests — temperature cycling, high-temperature reverse bias, and ESD — required for under-hood and chassis-mounted electronics.
Clamping performance and pulse handling
The 1500W rating at 10/1000µs is the standard telecom and automotive pulse shape — the part can handle shorter, higher-energy transients proportionally.
Housed in a DO-214AB (SMC) package, the part is surface-mount with a standard footprint. Supplied in tape and reel for automated pick-and-place; the bidirectional marking is a single band on the body, so orientation is not polarity-sensitive — no risk of a flipped part in rework.
No official second-source or pin-compatible alternative is recorded — the 1.5SMC33CAHR7G is the sole order code for this specific breakdown and package combination in the 1.5SMC family.
