1500 W surge clamp for 145 V rails
The 1.5SMC170CAHM3_A/H: AEC-Q101 qualification puts this part in the automotive-grade bucket: it has passed the reliability stress tests and temperature cycling required for under-hood and chassis-mounted electronics. The -65°C to 150°C junction temperature range covers cold-crank and hot-soak conditions without derating the surge capability.
Package and reflow fit
Housed in the DO-214AB (SMC) package, this is a standard surface-mount footprint that places flat on the pad with good coplanarity — no tombstoning risk if the stencil aperture and reflow profile match the solder paste volume. Tape & Reel packaging feeds directly into a pick-and-place machine; no special handling beyond the standard MSL bake check before reflow. The bidirectional channel means a single device protects both polarities on the same line, saving one diode per protected rail compared to a unidirectional pair.
Sourcing and compliance posture
The part carries the TransZorb® trademark and is built for automotive and telecom applications. Compliance documentation — RoHS, REACH, and the AEC-Q101 qualification report — is available from Vishay.
