The 1.5SMC30A-E3/57T: With a 25.6V reverse standoff and 41.4V clamping at 36.2A peak pulse current, it clamps transients on 24V nominal DC buses — common in industrial control, telecom, and power supply outputs.
The 1.5SMC series has broad industry penetration, so second-source equivalents exist from other major TVS manufacturers, though no pin-compatible direct replacement is documented in this listing.
With a 25.6V reverse standoff voltage, it is designed for 24V nominal DC rails. The minimum breakdown is 28.5V, and it clamps at 41.4V maximum during a 36.2A peak pulse transient.
