Automotive-grade surge protection for 154V rails
The 1.5SMC180AHM3/I: Its 154V reverse standoff voltage and 171V minimum breakdown voltage place it on a nominal 150V–160V DC bus, clamping transients to 246V maximum at the 6.1A peak pulse current.
Package and thermal envelope
Housed in the DO-214AB (SMC) surface-mount package, the part occupies the standard footprint for this power class — the same pad layout used across the 1.5SMC family. The operating junction temperature range spans -65°C to 150°C, covering the full automotive temperature grade without derating concerns at the high end. Tape-and-reel packaging suits automated pick-and-place assembly.
