1500 W surge clamp for 15.3 V rails
The 1.5SMC18CAHM3_A/I: With a 15.3 V reverse standoff voltage, it protects 12 V and 15 V DC rails from transients up to 25.2 V clamping at 59.5 A peak pulse current. The 1500 W rating means this part absorbs a single surge event without failing — useful for automotive load-dump, inductive kickback, and telecom line transients where the energy is high but short-lived.
AEC-Q101 grade for under-hood and chassis electronics
Qualified to AEC-Q101, the automotive discrete semiconductor stress test standard. The -65°C to 150°C junction temperature range covers engine-bay ambient and cold-crank conditions without derating the surge capability.
Active production — no end-of-life watch needed
The Tape & Reel packaging aligns with high-volume pick-and-place lines.
