Product details

Automotive-grade TVS for 12V rail clamping

The 1.5SMC10AHE3/57T: It clamps transients at 14.5V maximum when the surge current hits 103A, protecting downstream electronics from load-dump and inductive kickback.

AEC-Q101 qualification and thermal envelope

Qualified to AEC-Q101, this part is screened for automotive reliability — 1000-hour high-temperature reverse bias, temperature cycling, and ESD robustness per the automotive-grade flow. The DO-214AB (SMC) package is a standard surface-mount footprint for 1500W TVS diodes. The copper lead-frame and molded body handle the thermal pulse of a 10/1000 µs surge without exceeding the 150°C junction limit — the key parameter is the clamping voltage at peak current, not the steady-state dissipation.

Sourcing and lifecycle posture

The part ships on tape and reel (7-inch reel, 850 pieces per reel typical for DO-214AB).
