The 1.5SMC24AHE3/57T: It clamps transients at 33.2 V maximum while conducting 45.2 A peak pulse current, protecting downstream electronics from automotive load-dump, inductive kickback, and ESD events. This margin protects sensitive ECUs, sensors, and infotainment modules from transients that would otherwise reach the silicon.
Automotive-grade transient protection
AEC-Q101 qualification means this part passed the automotive stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the automotive discrete semiconductor standard. The DO-214AB (SMC) package delivers the 1500 W rating in a surface-mount footprint that reflows alongside standard passives. No power line protection is built in — this is a dedicated transient suppressor, not a crowbar or filter — so it pairs with an upstream fuse or e-fuse for coordinated protection.
The Tape & Reel (TR) packaging suits high-volume pick-and-place assembly. The base product number 1.5SMC24 covers the full family; the /57T suffix denotes the reel and packaging variant.
