Device identity and key ratings
The 1.5SMC27CAHE3_A/I: The 37.5 V clamp means a 23.1 V rail sees the transient clipped to under 38 V — enough margin for a 40 V-rated downstream IC without adding a second protection stage.
Automotive qualification and operating range
AEC-Q101 qualified, this part meets the automotive-grade stress and reliability screening required for under-hood and chassis-domain electronics.
