Product details

AEC-Q101 Zener TVS for 40 V rails

The Vishay 1.5SMC47AHM3/H is a Zener-type transient voltage suppressor from the 1.5SMC series, qualified to AEC-Q101 for automotive applications.

Automotive temperature and package fit

The DO-214AB (SMC) surface-mount package provides a low-inductance path for fast transients and a large copper pad area for heat sinking during the pulse. The part is unidirectional — one channel per device — and does not include power line protection features (no internal series element). It is a shunt-only clamp, so the PCB layout must keep the trace inductance between the protected rail and the cathode low.

The tape-and-reel packaging (TR) is the standard delivery format for high-volume pick-and-place assembly.
