1500 W peak pulse, AEC-Q101 qualified
The 1.5SMC150AHE3/57T: It clamps transients at 207 V maximum with a 128 V reverse standoff voltage, protecting downstream circuits from surges up to 7.2 A peak pulse current.
Clamping window and package fit
Breakdown occurs at 143 V minimum, clamping at 207 V — the 64 V window between standoff and clamp ensures the protected rail stays within safe limits during a 1500 W surge event. The single unidirectional channel handles one polarity; for bidirectional protection, pair two devices or select the bidirectional variant in the same series. DO-214AB (SMC) surface-mount package with a standard footprint — the same body as the SMCJ suffix. The Tape & Reel delivery suits automated pick-and-place assembly. No power line protection means it is intended for signal or low-voltage DC rails, not AC mains.
Active lifecycle, automotive supply chain
The base product number 1.5SMC150 covers the full family — the AHE3 suffix denotes the AEC-Q101 qualified variant with the 150 A surge rating.
