Product details

The 1.5SMC7.5AHM3/I: The 133 A peak pulse current rating is the current ceiling the clamping action delivers into the load — not a continuous rating, but the surge event the diode survives.

Automotive thermal zone deployment

Automotive-grade TVS is selected for the surge environment defined by ISO 7637-2, not just the steady-state voltage. Package is DO-214AB (SMC) in Tape & Reel — the standard SMC footprint accepts a thermal pad under the body for heat spreading, which matters when absorbing a 1.5 kW surge even as a pulsed event.
